Hi,
Have you tried regular expressions ? try them, they might do the trick

Hello people!!!
I would like to check if a string contains only numbers, I really can’t realize how to do it.
I tried is_int(), but it don’t work because the variable is a string (I used gettype() to check it) and is_int() returns NULL…
It is to validate some data in a form. The variable I’m trying to test is the result of this script:
$data = $_POST[‘data’]; // something like 123.456.789
$dataParts = explode($data);
//these are the variable I have to check:
$dataP1 = $dataParts[0];
$dataP2 = $dataParts[1];
$dataP3 = $dataParts[3];
gettype($dataP1), gettype($dataP2) and gettype($dataP3) return string
gettype($dataParts) returns array
Thanks in advance.
