Answer 1

How about something like this: http://(?:www\.)?imdb.com/title/tt[^/]+/.

Example:

<?php

if ( preg_match('#^http://(?:www\.)?imdb\.com/title/tt[^/]+/$#', 'http://www.imdb.com/title/tt0448303/') )
  echo 'Matches' . PHP_EOL;

Explanation:

The regular expression matches a string that starts with http:// followed either by imdb.com or www.imdb.com, then /title/tt followed by any character except for a / and that ends with a /.

The # is the delimiter, the ^ indicated the beginning of the string and the $ the end.
