$re = "/^.+?(?=\\s*[(.]?(\\d{4}))/mi"; 
$str = "\n\nBirdman.2014.DVDSCR.X264-PLAYNOW.mkv\n\nDivergent (2014) 720p Blu-Ray x2649 [Dual-Audio][English DD 5.1 + Hindi DD 5.1] - Mafiaking - TeamTNT ExClusive.mkv\n\nCradle 2 The Grave 2003 HDTVRip 720p Dual-Audio[Eng+Hindi] ~ BRAR\n"; 

preg_match_all($re, $str, $matches);
