Question

I need a good validation for tild(~) and tilt(`) character in PHP and Jquery.
Here is the Jquery validation what i have made.

$.validator.addMethod("validSMS", function(value, element) {
    if (value.indexOf('~') === -1 || value.indexOf('`') === -1)
    {
        return true;
    }
    else
    {
        return false;
    }
}, "Tild and tilt Character is not allowed");

But I need another good method for this validation in Jquery and in PHP also.

Answer 1

This is the php version, using strpos

if (strrpos($mystring, "~") === false && strrpos($mystring, "`") === false ) { 
    // $mystring has no tild(~) and tilt(`) chars
}
