Can't tell you what your problem is, but FWIW here is what I use to do
the job - if you can extract some useful bits from that....
<?php
function get_title($target) {
/* This little function will open the file passed in as $target and
extract the TITLE
tag and the text contained therein. If nothing is found it returns a
default value. */
$contents = File($target);
$exists=0;
$title = "";
for($i=0; $i < count($contents);$i++){
if(eregi("<TITLE>", $contents[$i])):
$exists=true;
endif;
if($exists):
$title .= $contents[$i];
endif;
if(eregi("</TITLE>", $contents[$i])):
break;
endif;
} /* End FOR */
/* Get rid of end of line in case title tag is spread over multiple
lines */
$title = eregi_replace(10, "", $title);
$title = eregi_replace(13, "", $title);
if( (empty($title)) || (strtoupper($title) == "<TITLE></TITLE>")):
$title = '<TITLE>Research Centre for Injury Studies</TITLE>';
endif;
/* Clear the slashes, in case there are wonky chars in the title
(Thanks, James!) */
return stripslashes($title);
} /* End function get_title */
?>
