numeric only

[remp]

Hello everyone, i have a contact form which has a phone number field, and i want to make it only number,

i have used the following code:

if (preg_match('/^[0-9]{1,}$/', $phone) < 4 ) {
        $error['phone'] = "Please enter your phone number.";
    } 

But for some reason, it does not work, can you give me a hand with this?

Use is_numeric().

Thank again.
