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!!!!

Not for me it doesn't. Returns false. Prolly because it's a string. Even the following returns false for me:
is_integer("12")
