Hello,

Basically, I am doing a fget() to get a remote page, then i need a regex (which i cant figure) to read the text between
<title> .. and </title>

for example:
<title> I am a fancy title </title>

running the regex should give me:
I am a fancy title

Thanks!

Forgot to escape.
preg_match('/<title>(.*?)<\/title>/', "<title> I am a fancy title </title>", $matches);
print $matches[1];
 
eregi('<title>(.*?)</title>', "<title> I am a fancy title </title>", $matches);
print $matches[1];

Hello,
I think you misunderstood me... I have no idea what the title will say, " I am a fancy title" was just an example.

It should work with any title...
unless thats what it already does..I have not tested your code as yet.. ;)

title may be upper and/or lower case letters. Make sure you do a case insensitive match:
$data = file_get_contents("http://www.somesite.com/somepage.html");
preg_match('/#<title>([^<]*)</title>#/iU',$data,$match);
$title=$match[1]; 
echo $title;

Hello Heilo,
I am getting this error when i run your code:

Warning: preg_match() [function.preg-match]: Unknown modifier 't' in C:\wamp\www\ezee\tests\get_remote_title.php on line 3

This is the entire code:
<?php
$data = file_get_contents("http://www.youtube.com/watch?v=oQ2dKXGAjNg");
preg_match('/#<title>([^<]*)</title>#/iU',$data,$match);
$title=$match[1];
echo $title;
?>
