PHP String Manipulation: Extract hrefs

by

You can use PHPs DOMDocument library to parse XML and/or HTML. Something like the following should do the trick, to get the href attribute from a string of HTML.

$html="<h1>Doctors</h1>
<a title="C - G" href="https://stackoverflow.com/questions/4702987/linkl.html">C - G</a>
<a title="G - K" href="link2.html">G - K</a>
<a title="K - M" href="link3.html">K - M</a>";

$hrefs = array();

$dom = new DOMDocument();
$dom->loadHTML($html);

$tags = $dom->getElementsByTagName('a');
foreach ($tags as $tag) {
       $hrefs[] =  $tag->getAttribute('href');
}
