Tim's code is good (thanks Tim), except it won't work very well if the tag is part of a
long non-breaking string.
E.g. try getting the title from Google Maps (http://www.google.com/maps).
A better solution is:
<?php
$title = "";
if ($fp = @fopen( $_POST['url'], 'r' )) {
$cont = "";
// read the contents
while( !feof( $fp ) ) {
$buf = trim(fgets( $fp, 4096 )) ;
$cont .= $buf;
}
// get tag contents
@preg_match( "/<title>([a-z 0-9]*)<\/title>/si", $cont, $match );
// tag contents
$title = strip_tags(@$match[ 1 ]);
}
?>
Note the strip_tags. Another thing to be careful of is to check for ", <, and >. You will
need to strip those out if you are posting the output to a form.
Also, it is probably best to use the /i modifier, because some people might code <TITLE>
etc...
