Regex & PHP - isolate src attribute from img tag

Question

With PHP, how can I isolate the contents of the src attribute from $foo? The end result I\'m looking for would give me just \"http://example.com/img/image.jpg\"

If you don't wish to use regex (or any non-standard PHP components), a reasonable solution using the built-in DOMDocument class would be as follows:

loadHTML('');
    $imageTags = $doc->getElementsByTagName('img');

    foreach($imageTags as $tag) {
        echo $tag->getAttribute('src');
    }
?>
