Problem with PREG_MATCH_ALL

[xsubs]

I'm trying to get GENRE from IMDB.com.

I made this code:

<?php 
$site = file_get_contents('http://www.imdb.com/title/tt0458522');

// Genre finding

preg_match_all("/<a href=\"\/Sections\/Genres\/(.*?)\/\">/si" , $site , $GenreArr); 
$SizeoGenre = sizeof($GenreArr[1]);
echo $SizeoGenre; 
$Genre = "";

for ($i=0;$i<=$SizeoGenre;$i++) {
		$Genre .= $GenreArr[1][$i];
	if ($i !== $SizeoGenre) {
		$Genre .= " / ";
	}
}
?>

 

But it returns Biography / Drama / Music /

(The problem is that it returns wrong number of "/" signs)

 

What can i do to solve this?

Is there another better way to to it?

 

Thanks.
