To echo (or display) an image using PHP, you typically need to set the correct headers and then output the image data. Here’s a step-by-step guide on how to do this:

Step 1: Create a PHP Script

Create a PHP file (e.g., display_image.php) that will handle the image output.

Step 2: Set the Correct Headers

At the beginning of your PHP script, set the appropriate content type header based on the image format (e.g., JPEG, PNG, GIF).

Step 3: Read and Output the Image

Use PHP functions to read the image file and output it. Here’s an example for a JPEG image:

<?php 
// Specify the path to the image 
$imagePath

To echo (or display) an image using PHP, you typically need to set the correct headers and then output the image data. Here’s a step-by-step guide on how to do this:

Step 2: Set the Correct Headers

At the beginning of your PHP script, set the appropriate content type header based on the image format (e.g., JPEG, PNG, GIF).

Step 3: Read and Output the Image

Use PHP functions to read the image file and output it. Here’s an example for a JPEG image:

<?php 
// Specify the path to the image 
$imagePath = 'path/to/your/image.jpg'; 
 
// Check if the image exists 
if (file_exists($imagePath)) { 
    // Set the content type header for the image 
    header('Content-Type: image/jpeg'); 
 
    // Read the image file and output it 
    readfile($imagePath); 
    exit; // Exit to prevent any additional output 
} else { 
    // Handle the case where the image does not exist 
    header('HTTP/1.0 404 Not Found'); 
    echo 'Image not found.'; 
} 
?>

Step 4: Access the Script

To display the image, you would access the display_image.php script in your web browser. For example, if your server is running locally, you might go to:

http://localhost/display_image.php

Notes

Make sure the path to the image is correct and that the web server has permission to read the file.
You can change the Content-Type header according to the image format you are using (e.g., image/png, image/gif, etc.).
This method is useful for dynamically serving images in applications, such as user uploads, where you may not want to expose the file path directly.

This approach allows you to control how images are served to users while leveraging PHP's ability to handle files and output data.

There are 2 ways, the first is straight forward & it might be what you’re looking for. You can just echo the url into an image tag?

<?php 
$imgUrl = "myimage.jpg"; 
?> 
<img src="<?= $imgUrl; ?>"/>

straight forward.

But if what your question asks, and you want to “echo an image”, you can use headers to set the mime-type / content-type as an image.

Here is a quick snippet in PHP,

<?php 
header('content-type: image/png'); 
$theImage = "myimage.png";//the real image url. 
echo file_get_contents($theImage); 
?>

Now, lets say the page above is “image.php”, when using an image tag, you can put “https://…/image.php” (https://…/image.php”) to

<img src="https://../image.php"/>

As with the first answer, I'm not sure what you're trying to achieve. PHP is a server side interpretive language used to produce html. With this in mind, (I'm guessing) what you're after is the same way that html "shows" an image; using the img tag. ie. html would simply be
<img src="smiley.gif" alt="Smiley face" height="42" width="42">

This can be achieved in PHP with;
echo '
<img src="smiley.gif" alt="Smiley face" height="42" width="42">';

If you want to echo image from file just use below code

echo '<img src="file path with extension"/>';

If you are retrieving image from database or it is in binary format you have to set header

header("content-type:image/jpeg");
echo $image;

Here $image contains the binary string of source image.

Overpaying on car insurance

You’ve heard it a million times before, but the average American family still overspends by $417/year on car insurance.

If you’ve been with the same insurer for years, chances are you are one of them.

Pull up Coverage.com, a free site that will compare prices for you, answer the questions on the page, and it will show you how much you could be saving.

That’s it. You’ll likely be saving a bunch of money. Here’s a link to give it a try.

Consistently being in debt

If you’ve got $10K+ in debt (credit cards…medical bills…anything really) you could use a debt relief program and potentially reduce by over 20%.

Here’s how to see if you qualify:

Head over to this Debt Relief comparison website here, then simply answer the questions to see if you qualify.

It’s as simple as that. You’ll likely end up paying less than you owed before and you could be debt free in as little as 2 years.

Missing out on free money to invest

It’s no secret that millionaires love investing, but for the rest of us, it can seem out of reach.

Times have changed. There are a number of investing platforms that will give you a bonus to open an account and get started. All you have to do is open the account and invest at least $25, and you could get up to $1000 in bonus.

Pretty sweet deal right? Here is a link to some of the best options.

Having bad credit

A low credit score can come back to bite you in so many ways in the future.

From that next rental application to getting approved for any type of loan or credit card, if you have a bad history with credit, the good news is you can fix it.

Head over to BankRate.com and answer a few questions to see if you qualify. It only takes a few minutes and could save you from a major upset down the line.

How to get started

Hope this helps! Here are the links to get started:

Have a separate savings account
Stop overpaying for car insurance
Finally get out of debt
Start investing with a free bonus
Fix your credit

What’s a little-known way homeowners can reduce their monthly bills?

A lot of people are overpaying on everyday expenses without even realizing it. Good news is, fixing it is way easier than you’d think.

With just a few smart moves, you could free up hundreds (maybe even thousands) of dollars. No extreme budgeting. No second job. Just a few tweaks to stop overspending and start saving.

1. You might be sitting on tens of thousands in home equity (without even realizing it)

If you’ve owned your home for a while, there’s a decent chance you’ve built up equity - money you could access when needed. Some people use a home equity line of credit (HELOC) to cover home proj

A lot of people are overpaying on everyday expenses without even realizing it. Good news is, fixing it is way easier than you’d think.

With just a few smart moves, you could free up hundreds (maybe even thousands) of dollars. No extreme budgeting. No second job. Just a few tweaks to stop overspending and start saving.

1. You might be sitting on tens of thousands in home equity (without even realizing it)

It’s not free money, though. A HELOC lets you borrow against your home’s value, so it only makes sense if you have a plan for the money. But if you’re paying high-interest debt while your home equity just sits there? It might be worth looking into.

Try comparing rates from different lenders before you decide. Here’s a popular site to compare rates: link.

2. Your car insurance company hopes you’re not shopping around for better offers

Insurance companies don’t exactly reward loyalty. In fact, they count on people sticking with the same policy year after year, even when cheaper options could exist.

Shopping around could save you hundreds. I managed to save around $1,300 for the exact same coverage. But comparing offers manually is a hassle, which is why comparison sites are becoming more popular.

If you haven’t checked in a while, it’s worth a quick look. Worst case? You confirm you’ve got the best deal.

Here’s the site I used to compare offers: Coverage.com - but Auto-Savings.com is solid too.

3. Get this company to get some of your debt forgiven

If you’re deep in credit card debt, you’ve probably seen ads promising to wipe it all away.

The reality is that debt relief companies can negotiate down what you owe, (depending on your situation).

For people struggling with $10k+ in unsecured debt, working with a legitimate debt relief company can sometimes lead to major reductions. Just be aware - this isn’t instant or magic.

You’ll still need to make payments, and it can impact your credit. But if you're feeling stuck, it’s an option worth checking out.

On average people who use a debt relief program get their debt reduced by 23% (after fees). Here’s a calculator if you want to see how much you could end up saving.

4. Find discounts when you shop online

Online shopping hacks are everywhere, and some actually work. Capital One Shopping is a browser extension that scans for lower prices and applies coupon codes automatically.

It’s not a miracle tool - sometimes there’s no discount to be found. But when it works, it works.

Plenty of people have saved on everything from tech to furniture without hunting down codes themselves.

It’s free to use, so there’s not much downside to trying it. Grab it here.

5. Get a company to pay your repair bills

If your appliances or HVAC system die unexpectedly, repairs can get expensive. That’s why some homeowners use a home warranty to cover unexpected breakdowns.

It’s not for everyone, but if you’ve got aging appliances and don’t want to shell out thousands for a sudden repair, it’s worth checking what’s covered.

Do your research, but this seems to be a highly rated company with a bunch of years operating: here’s a link to their site.

6. Get a financial advisor (a good one will pay for itself)

Financial advisors aren’t just for millionaires. The right one can help with tax planning, investing, budgeting, and long-term financial goals.

That said, not all advisors are created equal. Some charge high fees without delivering much value.

But the good ones? They can help you make smarter money moves and potentially see better returns than going it alone. If you’re curious, it might be worth chatting with an advisor to see if they’re actually useful for your situation.

Use a site like this one to find a local advisor with good reviews (if you don’t know one personally).

I am not sure what you want to achieve but what you can do is to echo the url of an image.

You can also use array and foreach loop to echo multiple images.

It's just like the normal img tag with the source of the file. The only difference here is that since you are using php, you have to use the echo statement. Example is echo "<img src =’imageaddress>

When is it a better idea to use print instead of echo in PHP?

I honestly can’t think of a single instance I would want to.

The only practical difference I can think of is that print() operates like a function that always returns 1.

You could in theory:

true && true && print ('hello');

Outputs:

hello

The following:

true && false && print ('hello');

Outputs:

Yup, nothing.

Let’s try this with echo.

The following:

true && false && echo ('hello');

Outputs:

PHP Parse error:  syntax error, unexpected 'echo' (T_ECHO) in test.php on line 2

Oh dear!

So let’s say I wanted to do a print out something if an IF statement is positive:

$i  = 0; 
if (true && true && print ('added')) { 
	$i +

I would find the following easier to read

$i  = 0; 
if (true && true) { 
	echo 'added'; 
	$i += 1; 
}

Conclusion

It does have it’s unique qualities, but I can’t think of a single place I’d actually use it. It would make the code less readable at the savings of only a few characters.

Readability is king in programming.

After Thought

Maybe there is 1 case in debugging a long if statement I could think of:

$a = 1; 
$b = 1; 
$c = 1; 
$d = 1; 
$e = 1; 
 
if ($a && $b && $c && $d && $e) { 
	echo 'User Signed In'; 
}

In the above code, how can you easily debug which is failing?

$a = 1; 
$b = 1; 
$c = 1; 
$d = 1; 
$e = 1; 
 
if ($a && print ("Got Past a\n") && 
	$b && print ("Got Past b\n") && 
	$c && print ("Got Past c\n") && 
	$d && print ("Got Past d\n") && 
	$e && print ("Got Past e\n") 
) { 
	echo 'User Signed In'; 
}

Unfortunately, this still doesn’t work as I would have expected, I get the output:

Got Past e 
1111User Signed In

After after thought

Just stick with echo, it’s also just 1 character less to be typed.

Why do all PHP developers use echo instead of print?

In PHP ; both ‘echo’ and ‘print’ are quite similar but there are bit differences.

One of the difference is ‘echo’ does not have any return value but ‘print’ has return value =1; if it success. So for that cause the execution time of program is naturally faster using ‘echo’ instead of ‘print’.
Another difference is you cant print multiple arguments separated by comma using ‘print’ . Follow below codes to better understand-

<?php 
echo "I am here<br>" , "with you"; 
print "<br>I am here"; 
?>

In above coding you cant get any syntax error .

Now again follow below code-

<?php 
echo "I am here<br>", "with you";

So those are two main differences . That is why might be all PHP developers use echo instead of print.

How can I insert an image on a PHP file?

This is a pretty basic question so I apologize if my answer gets too simplistic.

For where you are at, you can think of a PHP file as just an HTML file that lets you occasionally interrupt the HTML layout to do something in PHP.

So if this is the HTML for a page with a single image:

<!DOCTYPE html> 
<html lang='en'> 
<head> 
    <title>Test Page</title> 
</head> 
<body> 
    <img src='path/to/myphoto.jpg' alt='photo of me' /> 
</body> 
</html>

Then this is that same page with a little PHP to output the HTML image tag:

<!DOCTYPE html> 
<html lang='en'> 
<head> 
    <title>Test Page</title> 
</head> 
<body> 
 
<?php 
    echo "<img

<?php 
    echo "<img src='path/to/myphoto.jpg' alt='photo of me' />"; 
?> 
 
</body> 
</html>

The PHP code starts where you see <?php and ends where you see ?>.

Just to expand the example a little, let’s say you wanted a PHP page to randomly show a picture of either you or your dog on each page load. That might look something like this:

<!DOCTYPE html> 
<html lang='en'> 
<head> 
    <title>Test Page</title> 
</head> 
<body> 
 
<?php 
    // Randomly assign either a 0 or 1 to the variable $show_my_dog. 
    $show_my_dog = rand(0,1);	 
 
    if( $show_my_dog == 1 ) 
        echo "<img src='path/to/mydog.jpg' alt='photo of my dog' />"; 
    else 
        echo "<img src='path/to/myphoto.jpg' alt='photo of me' />"; 
?> 
 
</body> 
</html>

Hope that helps get you started!

Currently I'm using 'echo "<a_html_tag>";', is this the "right" way to add elements to a web site in PHP?

This works, and can be called a right way but there are other ways for as and when the situation may demand.
For example,

You can break the php code like this:

<?php if(condition){ ?>  
    <!-- HTML here -->  
<?php } ?>

But this is more suitable for displaying larger HTML content. Can also be used without the conditional statement.

Alternatively, you may utilize the heredoc syntax supported in php5+, as follows:

echo <<<ABC 
This can be any HTML or general string content with variable interpolation 
ABC;

Here, ABC can be any random characters. But make sure to NOT indent the closing 'ABC;' and NO whit

Or, you can just assign the html string to a variable and then echo the variable.
There is no one "right" way. :)

Currently I'm using 'echo "<a_html_tag>";', is this the "right" way to add elements to a web site in PHP?

Depends on what you mean by "add elements to a web site". If your simply adding a div, the correct way to add it in a PHP website is the same way you add it in a raw HTML website. That is, <div></div>. If however, you are building something dynamic, or something that requires back-end data, then you may desire other options. In this case

echo '<div></div>';

would be perfectly acceptable

as in

$file_list = FileManager::getListofReports();  
foreach ($file_list as $file) {  
     echo '<div><a target="_blank" href="echo $file">echo $file</a></div>'; 
}

or, a combination of both, as in:

$file_list = FileMan

echo '<div></div>';

would be perfectly acceptable

as in

$file_list = FileManager::getListofReports();  
foreach ($file_list as $file) {  
     echo '<div><a target="_blank" href="echo $file">echo $file</a></div>'; 
}

or, a combination of both, as in:

$file_list = FileManager::getListofReports();  
foreach ($file_list as $file) { ?> 
<div style="padding-right: 15px;"> 
     <a style="color: #fff;" target="_blank" href="<?php echo '$file' ?>"><?php echo $file ?> 
     </a> 
</div> 
<?php } ?>

In PHP, is echo used for display and for inputting a value?

Yes, echo is the more commonly used form of putting data on the screen. But you want to be careful when you use it that the data being output is sanitary. Meaning something that can't break the environment it's running in. Example a web page if you echo HTML that is based on a users input the I can use that input to create an elaborate page within your page and potentially hijack your site then eventually maybe even your server santized means you are treating everything a user can input as hostile and are using HTML entities and encoding and other methods to scrub data clean to prevent it from

How are arrays echoed in PHP?

The obvious answer is print_r (or var_dump) as answered by many people. But take this tip from a ~17-year PHP geek. The problem with the output from print_r or var_dump is it is not re-usable in any way. You can’t copy/paste the output into a variable definition and expect to be able to re-use it. When I’m quickly hacking through things, sure, I’ll echo things. But over the years I’ve converted and anything more complex I’ve gotten in the habit of instead using json_encode instead of print_r. And if you want it to look sexy, use the pretty print option.

Here, let me show you how and why…

$arr =

Here, let me show you how and why…

$arr = array('one', 'two', 'three'); 
echo json_encode($arr, JSON_PRETTY_PRINT);

Will output…

[ 
    "one", 
    "two", 
    "three" 
]

Which you can copy/paste right back into PHP to use. For example…

$arr = json_decode([ 
    "one", 
    "two", 
    "three" 
]); 
print_r($arr);

Will output…

Array 
( 
    [0] => one 
    [1] => two 
    [2] => three 
)

This is in my opinion, far superior to print_r/var_dump, as you’ll be able to for example, take the output of a function, and re-use it over and over for debugging the next step in the logical flow of an application when you’re stepping through your code. Take it from an hardcore php veteran. :)

PLEASE NOTE: This does not work on OBJECTs, for that you should use PHP’s serialize() so you can unserialize them, but then they become _nearly_ unreadable again. But if you know your data is an array or simple object and you don’t care about being able to replicate it, then it’s okay to json encode it. :)

Cheers!

Which is better, echo or print in PHP?

echo and print both are PHP Statement are used to display the output in PHP.

echo

echo is a statement i.e used to display the output. it can be used with parentheses echo or without parentheses echo.
echo can pass multiple strings separated as ( , )
echo doesn’t return any value
echo is faster than print
eho is not a function but a language construct.

print is also a statement i.e used to display the output. it can be used with parentheses print( ) or without parentheses print.
using print can doesn’t pass multiple argument
print always return 1
it is slower than echo
In PHP, print is not a real fun

Can I send an image using PHP?

You'd need to define "send". If you mean, can I send an image to the server (upload)? Then yes, quite easily.

Can I send an image in an email by PHP? Possibly, you'd need to use an upload script to upload it, then create an email, attaching the image to the email and sending it. It is possible but difficult.

The third option would be emailing it to an address not...

What is the difference between print & echo in PHP?

Speed: There is a difference between the two, but speed-wise it should be irrelevant which one you use. echo is marginally faster since it doesn't set a return value if you really want to get down to the nitty gritty.
Expression: print() behaves like a function in that you can do: $ret = print "Hello World"; And $ret will be 1. That means that print can be used as part of a more complex expression where echo cannot. An example from the PHP Manual:

$b ? print "true" : print "false";

print is also part of the precedence table which it needs to be if it is to be used within a complex expression. It

print is also part of the precedence table which it needs to be if it is to be used within a complex expression. It is just about at the bottom of the precedence list though. Only "," AND, OR and XOR are lower.
Parameter(s): The grammar is: echo expression [, expression[, expression] ... ] But echo ( expression, expression ) is not valid. This would be valid: echo ("howdy"),("partner"); the same as: echo "howdy","partner"; (Putting the brackets in that simple example serves no purpose since there is no operator precedence issue with a single term like that.)

So, echo without parentheses can take multiple parameters, which get concatenated:

   echo  "and a ", 1, 2, 3;   // comma-separated without parentheses 
   echo ("and a 123");        // just one parameter with parentheses

print() can only take one parameter:

   print ("and a 123"); 
   print  "and a 123";

Hope this helps :)

When is it a better idea to use print instead of echo in PHP?

print and echo are really based on preference. I prefer to use print because majority of programming languages use print. The only one that comes to mind that uses echo is Bash. So I prefer using print because I don’t have to switch between print and echo when I use multiple different languages. I can just simply use 1 command that is universal in other languages. Also, echo like many PHP commands are heavily abused and people really don’t understand the real main use behind it or any of its drawbacks.

How do I scan images from a URL using PHP?

You wouldn’t scan them, but retreive them.

A simple way would be to create a page with a form:

Enter target URL or have a bookmakrlet to do this part for you
Retrieve the page
PHP: cURL - Manual or
file_get_contents - Manual
Parse out the images from the HTML -
PHP: DOM - Manual
Download the images using, say, curl again or even just copy
PHP: copy - Manual

How can I insert an image on a PHP file?

You can insert an image in PHP file by using HTML tags. Syntax is similar to HTML you can use echo to print the image but the total HTML must be present inside the PHP tags.

I stated two ways to do this work any of the two Will work but make sure when should you use the particular syntax, you Will understand this only if you know the use case of each of them.

You can do this by simply using image tag in php

echo ' <img src="php.png" /> ';

You can also do this by inserting html tags inside

<?php and ?>

<div> 
 <img src="myPic.jpg" alt="myPic" /> 
 </div>

How can I display an image from a database in PHP?

You don’t do it directly with PHP. PHP is a server side language.

You need to use PHP to generate the HTML and send it to the browser.

The image itself should not be in the database. That’s a very bad idea. You usually have the image on the file system. The path and the image name are what is saved in the database.

You call that up from the database, and use it to genera...

Why do we have to use "echo" in PHP, while we can print words out without it?

PHP has some redundant stuff, which probably was introduced to make things easier, if that really helps is doubtful.

In PHP you can use the inline code structure to echo variables <?=$var ?>

as well as with echo when you use it inside php code.

In general using echo statements is not good style, html/php mixed files are horribly difficult to debug and stand a good chance of getting injection issues when it is not done properly. Using a template language or using views in a framework is usually better.

What is the difference between echo and print in PHP?

Before checking the difference between these two, lets look into little deep.

echo and print() are language constructs .

That means the php compiler knows the exact syntax of the echo/print() statement. Unlike built in functions, language constructors act like some keywords, they already defined by the compiler.

Other main advantage of language constructor over built in function is, it’s little more faster than built in functions.

Now lets come to the answer, both these statements are used to print a value.

Main differences are

echo do not return anything while print() return a value(1)

$var a = echo

$var a = echo “something”; //return error since echo return no value; 
$var b = print(“somethning”); //return 1

Multiple values passed to echo, but only one value can pass to print()

echo “something”,100,3.14,’A’; 
print(“something”,1,3.14); //shows error

Echo is much more faster than print()

In PHP echo simply output whatever is passed to it as parameter.

echo 'hello world' //It will show hello world

echo 'hello $name' // it will show hello Jon if $name=Jon

How do I add an image seen in PHP code?

To make the image has viewed by the user we can make one table seperately and on click that image update the coloumn by some Flag like ' S' or 'N' . S for seen and N for Not seen which can be by default set to N for all the users.

TableName : Image_Seen

Coloumn Name : Userid , imageid , Status (Set by default N ) on click image or using some jQuery when user scrolls on images update the coloumn STATUS value to ‘S’.

To Show on user side wheather image has been seen or not seen. Check from database Using Imageid it is Still 'N' - Not seen or 'S'- Seen.

This would be better using jQuery,AJAX,PHp

What is the PHP echo function?

Literally displays whatever text you tell it to. To get more complicated... It will also echo the type if you give it an array (unless they changed it).

Google print vs echo for some more details, as they do have their limitations. And the speed depends on the type of variable you give the function.

Now assume that “user1” is the person viewing the image and “user2” is the person who posted that image,

When user1 clicks the image add a jquery/ajax code to pass the user1’s name to the table of image and store in the column of image_status.

Now, at the image display page add a <span> tag and in that you have to perform check of following things:

check if the “user_status” column is empty or not, if not empty echo “seen”.

If you want to add the number of users viewed the image(this will be public), just add a query “SELECT count(image_status) FROM image_table WHERE image_id= “pass-the-current-image-id-here”.

Now add another span tag and echo the result in that tag and you’ll get the number of views of the image.

Hope this helps.

Which is better, echo or print in PHP?

both are more or less the same. The main difference is that print has a return value of 1 so you can use it in expressions. This is also the reason why echo is faster (no return value)
