Get image url from content containing an image

Question

I am building a small cms system for personal use. A part of it requires me to get the first image url in an article. How can I do this?

Sample article content in variable $article

<p>
<img src="/images/userContent/2013-07-12%2022_27_34.png">
The griefing problem has been curbed!
</p>

How can I get the url /images/userContent/2013-07-12%2022_27_34.png
Possibly regex? if yes, how? I am clueless with regex

Using regular expressions to parse (X)HTML will cause an encounter with [Cthulhu](http://www.codinghorror.com/blog/2009/11/parsing-html-the-cthulhu-way.html). — Mike, Aug 15 '13 at 21:29

Use the DOMDocument class:

<?php
    $myhtml = '...'
    $doc = new DOMDocument();
    $doc->loadHTML($myhtml);
    $imageTags = $doc->getElementsByTagName('img');

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

Output:

/images/userContent/2013-07-12%2022_27_34.png
