Question

How can I fetch all images src into array with file_get_content(), with preg_match or whatever?

Answer 1

You shouldn’t use regex to parse HTML. You should use classes like DOMDocument to do so. DOMDocument has the getElementsByTagName method that can be used to retrieve all the img tag from the document you want to parse.

Here’s an example that will echo the list of the images in the document :

<?php
    $document = new DOMDocument();
    $document->loadHTML(file_get_contents('yourfilehere.html'));
    $lst = $document->getElementsByTagName('img');

    for ($i=0; $i<$lst->length; $i++) {
        $image = $lst->item($i);
        echo $image->attributes->getNamedItem('src')->value, '<br />';
    }
?>
