Please help me correct the regular expression for the preg_split() function.

 preg_split('/^(photo)*([0-9])+_/','photo1542_123')

It is necessary that the string photo1542_123 broken into an array

 `Array ( [0] =>photo [1] => 1542 [2] => 123 ) `.

    Mike is right preg_match('/^(photo)(\d+)_(\d+)$/','photo1542_123', $m) should return what is needed in $m[1] - cyadvert
