It's not that killing... :p preg_match("#^-?[0-9]+$#",$_POST["var_int"]);

Not *that's* a mouthful ...

I was also thinking about that === operator.. And this: if(((string)((int)$_POST["var_int"]))==$_POST["var_int"])

Cute. Might actually work too! Wonder if there would be any difference in using == or === in your suggestion? Jc
