Re: variable type - conversion/checking

Hi, I have tried to find a way to check if a character string is possible to test whether it is convertible to an intger ! any suggestion ? BR georg

All responses in this thread have been very nice; but you could also try a much simpler 2-step check: 1. is_numeric 2. if true > check if there's a decimal character in the string: if(is_numeric($str) && false === strpos('.', $str)) { // it's an int for sure } else { // might be a number, but it's definitly not an int }
