Christoffer's code is great. Just to minor things:
- declare $match to avoid warnings on error_reporting = E_ALL environments (also because 'explicit is better than implicit')
- cosmetic changes to adjust to Zend's code style (a matter of personal opinion)
<?php
function getTitle($htmlPage)
{
$match = array();
return preg_match('/<title>(.+?)</title>/i', $htmlPage, $match) ? $match[1] : 'No title';
}
?>

In my code, I needed to escape the forward slash in the closing title tag.
<?php
function getHtmlTitle( $htmlPage, $default = 'No Title' )
{
$match = array();
return preg_match( '/<title>(.+?)<\/title>/i', $htmlPage, $match) ? $match[1] : $default;
}
?>
Extract and return the bits between the <title> and </title> tags of an html page.
