Hi,

following works for me:

$string = "12";
echo $string+1; //Outputs 13

I hope it helps,

You could also try settype

settype($var, "integer");

Hi,

you could also use intval() http://www.php.net/manual/en/function.intval.php

A lot of mucking around - whenever PHP sees a variable or literal in a situation where it expects an integer, it will treat it as an integer.

print "12"+"40";

returns 52
