Re: problem with intval and !=

Cesar, You can take a look into is_numeric () (http://www.php.net/is_numeric). It will tell you whether the value is a number or a numeric string, but it will also return true if the value is a float. However, at that point you know your working with the right type of variable.

Sorry, typo, this is what I meant, !is_integer("12thisisnotanumber") retuns true. but also, is_integer("12") return false. therefore, is_integer(12) return true. So, how can I check if what ever the user writes is an integer or not, knowing that he will write it in a string field. Any how, I solved the problem with preg_match("/^([0-9]+)$/", $value) Thanks for your help, list!!!! =) Robert Cummings wrote:

Not for me it doesn't. Returns false. Prolly because it's a string. Even the following returns false for me:

    is_integer("12")
