php regex changing split to preg_split - specific example

Lots of questions similar but I have a specific example I would like some help with please. Migrating older php 5.2 code to 5.3

for($s=0;$s<count($tmp=split("/",$check_for));$s++)

assumed would be

for($s=0;$s<count($tmp=preg_split("///",$check_for));$s++)

However, I get 

Warning: preg_split() [function.preg-split]: Unknown modifier '/'

Can someone give me some direction please? Thank you.

Solution

  • The first character of a preg_XXX pattern is the separator which separates the pattern from the options that follow. Therefore, you cannot use the separator in the pattern itself without escaping it.

    Consider using a different separator, like ~:

    for($s=0;$s<count($tmp=preg_split("~/~",$check_for));$s++)
