php - Separating the non-numeric part of an alphanumeric string -

-

i have set of alphanumeric strings, each beginning non-numeric characters , ending numbers, want able separate non-numeric parts numeric parts, assuming number of characters constant each string, have been easy have strings abc123, abcd456, etc.

i this:

<?php $strarray = array(); $strarray[] = '123abc'; $strarray[] = 'abc123'; $strarray[] = 'abcd456'; $strarray[] = 'abc4567'; $strarray[] = 'abcd4567';  foreach ($strarray $str){     preg_match('/^([a-za-z]+)([0-9]+)$/', $str, $matches);     if (count($matches)===3){         $alphapart = $matches[1];         $numericpart = $matches[2];         var_dump($alphapart);         var_dump($numericpart);     }     else{         echo 'no match: ' . $str;     } } ?>

i prefer more specific definition of pattern for. , suspect preg_split worse approach, performance wise. @ least, consider overkill if there 2 parts split string int0.
