PHP preg_match numbers length

Question

I'm trying to validate phone numbers and am struggling with this code. When I input a mobile number(0-9) with a length of either 10 or 11 I get invalid mobile number. Any ideas?

if (!preg_match('[0-9]{10,11}', $mobileNumber)) {
    echo("invalid mobile number");
    exit();
}

I believe you're missing the regex delimiters:

if (!preg_match('/[0-9]{10,11}/', $mobileNumber)) {
    echo("invalid mobile number");
    exit();
}

And I believe you forgot the start and end anchors `^$` – HamZa Dec 03 '13 at 16:47
