    $imdb = file_get_contents('http://www.imdb.com/title/tt4600952/?ref_=nv_sr_1');

    $sourcecode = htmlentities($imdb);

    preg_match('/<h1 itemprop="name" class="">([a-zA-Z0-9\:\'\ ]+)/', $sourcecode, $title);

    var_dump($title);

Remove the `$sourcecode = htmlentities($imdb);` line as it encodes some special chars. – Wiktor Stribiżew Mar 31 '18 at 17:54
if so it now return wrong match. – daivd rush Mar 31 '18 at 17:56
That is quite expected, do not use regex to parse HTML. – Wiktor Stribiżew Mar 31 '18 at 17:57
`/
([a-zA-Z0-9\:\'\\\ ]+)/` your missing 2 \\ backslashes it takes 3 backslashes ( 1 for PECL, 1 for PHP and the original) to do a backslash. regx101.com doesn't account for this issue. Not sure if it will make a difference though.
