How can PHP be used to pass variables to image sources and avoid the need to extract them from images later?

When passing variables to image sources in PHP, you can use query parameters in the image URL to dynamically set the variables. This way, you can avoid the need to extract them from the images later. By appending the variables to the image URL, you can easily access them using the $_GET superglobal in PHP. 

<?php
// Define the variables to be passed
$imageId = 123;
$imageSize = 'large';

// Construct the image URL with query parameters
$imageUrl = 'https://example.com/image.php?id=' . $imageId . '&size=' . $imageSize;

// Output the image tag with the dynamic image URL
echo '<img src="' . $imageUrl . '" alt="Dynamic image">';
?>
