I am recieving the following error:

Notice indefined offset 1: in C:\wamp\www\includes\imdbgrabber.php line 36

the code is for getting information from IMDB. The link is posted to the page using ajax on another page, I have tested that i am getting the correct response using echo $url

    <?php

$url = $_GET['link'];

echo $url;

//$url = 'http://www.imdb.com/title/tt0367882/';

//get the page content
$imdb_content = get_data($url);

//parse for product name
$name = get_match('/<title>(.*)<\/title>/isU',$imdb_content);
$director = strip_tags(get_match('/<h5[^>]*>Director:<\/h5>(.*)<\/div>/isU',$imdb_content));
$plot = get_match('/<h5[^>]*>Plot:<\/h5>(.*)<\/div>/isU',$imdb_content);
$release_date = get_match('/<h5[^>]*>Release Date:<\/h5>(.*)<\/div>/isU',$imdb_content);
$mpaa = get_match('/<a href="\/mpaa">MPAA<\/a>:<\/h5>(.*)<\/div>/isU',$imdb_content);
$run_time = get_match('/Runtime:<\/h5>(.*)<\/div>/isU',$imdb_content);
$rating = get_match('/<div class="starbar-meta">(.*)<\/div>/isU',$imdb_content);

////build content
//$content = '<h2>Film</h2><p>'.$name.'</p>'
//          . '<h2>Director</h2><p>'.$director.'</p>'

//gets the match content  
function get_match($regex,$content)  
{  
    preg_match($regex,$content,$matches);  
    return $matches[0];
