Its not a perfect solution, but if you're can't or don't want to use the ctype
functions, you can test to see if something is an integer by doing something like this:<br>
<br>
if ( $var != "0" && $var / 1 == 0 ) { }<br>
<br>
it seems redundant, but you're checking to be sure that $var is not the string representation
of 0 first, and then finding out if $var is divisible by itself.
