What is the correct way to include PHP code in the src attribute of an img element in HTML?

When including PHP code in the src attribute of an img element in HTML, you need to make sure that the PHP code is processed on the server before the HTML is sent to the browser. This can be achieved by using a PHP file to generate the image content dynamically and then referencing that file in the src attribute of the img element.

<!-- HTML code with PHP included in the src attribute -->
<img src="image.php" alt="Dynamic Image">

// image.php
<?php
// Generate image content dynamically
header('Content-Type: image/jpeg');
$im = imagecreatefromjpeg('image.jpg');
imagejpeg($im);
imagedestroy($im);
?>
