Regex & PHP - isolate src attribute from img tag

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 ""

$foo = '<img class="foo bar test" title="test image" src="" alt="test image" width="100" height="100" />';

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:

    $doc = new DOMDocument();
    $doc->loadHTML('<img src="" ... />');
    $imageTags = $doc->getElementsByTagName('img');

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