How can PHP be used to extract and separate images from text within a variable for display on a webpage?

To extract and separate images from text within a variable in PHP, you can use regular expressions to identify image tags and extract the image URLs. Once you have the image URLs, you can display them on a webpage using HTML img tags. 

<?php
// Sample variable containing text with images
$text = "This is an example <img src='image1.jpg'> text with <img src='image2.jpg'> images.";

// Use regular expressions to extract image URLs
preg_match_all('/<img src=\'(.*?)\'>/', $text, $matches);

// Display the images on the webpage
foreach ($matches[1] as $image) {
    echo "<img src='$image' alt=''>";
}
?>
