[PHP] preg_replace is modifying the type of replacement parameter !!

Hmmm, RegEx work on strings, so the engine needs strings. Because of that your integers are converted to strings, if you want to give their life back make foreach ($arr as $k=$v){ $arr[$k]+=0; } Now all are integers. Andrey Hristov IcyGEN Corporation http://www.icygen.com BALANCED SOLUTIONS
