Description:
------------
preg_match will match against 'ourproducts/documentaries/test12345.html' 
but not against 'ourproducts/documentaries/test123456.html'

preg_match_all does return the expected result, however.

Reproduce code:
---------------
$result = preg_match('#^((?:[^/]+/?)+)/(.*)$#i','ourproducts/documentaries/test123456.html',$matches);

var_dump($matches);

Expected result:
----------------
array(3) {
  [0]=>
  string(40) "ourproducts/documentaries/test123456.html"
  [1]=>
  string(25) "ourproducts/documentaries"
  [2]=>
  string(14) "test123456.html"
}

Actual result:
--------------
array(0) {
}
