<a class="link interlink" rel="&content_type=topic&content_type_id=21579" href="http://www.associatedcontent.com/topic/21579/fannie_mae.html" title="Fannie Mae" onClick="var s=s_gi('assoccontdev');
		s.tl(this,'o','art_interlink');
		if(s.prop20) s.prop30=s.prop20;
  		if(s.prop29) s.prop31=s.prop29;
		s.linkTrackVars='prop30,prop31'; ">Fannie Mae</a>

I want to get the href link and anchor text

I used this which don't seem to be working

$regex_pattern = "/<a(.*)\">(.*)?<\/a>/U";

If you need any and all attributes of the <a> tag use:

$string = '<a class="link interlink" rel="&content_type=topic&content_type_id=21579" href="http://www.associatedcontent.com/topic/21579/fannie_mae.html" title="Fannie Mae" onClick="var s=s_gi(\'assoccontdev\');
        s.tl(this,\'o\',\'art_interlink\');
        if(s.prop20) s.prop30=s.prop20;
          if(s.prop29) s.prop31=s.prop29;
        s.linkTrackVars=\'prop30,prop31\'; ">Fannie Mae</a>';

$regex = '~<a(.*)>(.*)</a>~iUs';
preg_match($regex, $string, $matches);
$linkTitle = $matches[2];

$regex2 = '~(.*)="(.*)"~iUs';
preg_match_all($regex2, $matches[1], $matches);

for($i=0; $i<sizeof($matches[1]); $i++)
{
	echo '<strong>'.$matches[1][$i].'</strong>: <pre>'.htmlspecialchars($matches[2][$i]).'</pre>';
}

If you only want href and the value of the <a> tag use:

<?php

$string = '<a class="link interlink" rel="&content_type=topic&content_type_id=21579" href="http://www.associatedcontent.com/topic/21579/fannie_mae.html" title="Fannie Mae" onClick="var s=s_gi(\'assoccontdev\');
        s.tl(this,\'o\',\'art_interlink\');
        if(s.prop20) s.prop30=s.prop20;
          if(s.prop29) s.prop31=s.prop29;
        s.linkTrackVars=\'prop30,prop31\'; ">Fannie Mae</a>';

$regex = '~<a.*href="(.*)".*>(.*)</a>~iUs';
preg_match($regex, $string, $matches);
$href = $matches[1];
$linkTitle = $matches[2];
echo $href.'<br />'.$linkTitle;

Of course, there's always the use of simpleXML if you can use it 😉

Going on extracting href and anchor text, an alternative could be to use DOM/Xpath:

$string = '<a class="link interlink" rel="&content_type=topic&content_type_id=21579" href="http://www.associatedcontent.com/topic/21579/fannie_mae.html" title="Fannie Mae" onClick="var s=s_gi(\'assoccontdev\');
        s.tl(this,\'o\',\'art_interlink\');
        if(s.prop20) s.prop30=s.prop20;
          if(s.prop29) s.prop31=s.prop29;
        s.linkTrackVars=\'prop30,prop31\'; ">Fannie Mae</a>';

$dom = new DOMDocument;
@$dom->loadHTML($string); // for a site, change loadHTML to loadHTMLFile and put the complete URL in the parenthesis
$xpath = new DOMXPath($dom);
$aTag = $xpath->query('//a[@href]');

foreach ($aTag as $val) {
    echo $val->getAttribute('href') . ' - ' .  $val->nodeValue . "<br />\n";
}

Output:
