PHP-General - Regular expression
PHP Code:
$link_text = 'Apply now';
$content = '<td align="right" class="apply"> <a href="http://domain.com?h=AJ&cm=Details_ApplyNow" onClick="ApplyNowClick(\'A7C6NP\');" title="Apply for this now!">Apply Now</a></td>';
$pattern = '|<a[^>]+>('.$link_text.')</[^>]+>|U';
preg_match($pattern, $content, $output);
$pattern = '/<[a]{1}(.*)?>(.*)<\/[a]{1}>/';
$content = trim(preg_replace($pattern, '$1', $output[0]));
... // then parse $content to get the href url
Is it possible to know what is wrong with the regular expression to get the href of this tag?
<td align="right" class="apply"> <a href="http://domain.com?h=AJ&cm=Details_ApplyNow" onClick="ApplyNowClick(\'A7C6NP\');" title="Apply for this now!">Apply Now</a></td>
Not getting anything in $output. I've this code working for a similar <a ..> tag.
Thanks!

Your match text has "now" but the link has "Now"

regex patterns must start with '/' and ends with '/' , and after the last '/' add an 'i' to make case insenstive
$pattern = '/regex/i'

yes you are right, its however appears to be the standered and better for script consistency imo
still though, the i modifier should make it case insensitive

This should do the trick.
PHP Code:
<?php
$content = '<td align="right" class="apply"> <a href="http://domain.com?h=AJ&cm=Details_ApplyNow" onClick="ApplyNowClick(\'A7C6NP\');" title="Apply for this now!">Apply Now</a></td>';
preg_match('#<a href="(.+)" onClick=".+" title=".+">Apply Now</a>#U', $content, $output);
var_dump($output);
?>
