Use queryPath, Simple HTML DOM Parser or other PHP libraries for navigating in DOM document

---

You can use PHP Query library, and attr method if you are familiar with CSS selectors.

<?php 
echo pq('a')->attr('href');

$html = <<< EOF
<a onclick="javascript:_gaq.push(['_trackEvent','outbound-article','namobile.naughtyamerica.com']);" href="http://www.wwww.com/track/MTA3ODQxLjEyLjQwLjQwLjAuMC4wLjAuMA/freeporn3/lisa_ann6/7535/"><img class="aligncenter size-full" title="Lisa Ann" src="http://www.www.com/upload/source/mfhm/lisawill/lisawillhor_gmna_big_img3.jpg" alt="Lisa Ann" width="313" height="223" /></a>
EOF;

preg_match_all('/<a onclick.*?href="(.*?)"/im', $html, $url, PREG_PATTERN_ORDER);
$url = $url[1][0];


echo $url // echo's "http://www.wwww.com/track/MTA3ODQxLjEyLjQwLjQwLjAuMC4wLjAuMA/freeporn3/lisa_ann6/7535/"
