How could I do

if phone number is not missing, it must be 13 digits long otherwise errflag comes on?

 

I've attempted several ways but none have worked 

 

This is what I have for the 13 digits part of the qry...

if(strlen($phone) <> 13) {
    $errmsg_arr[] = 'Phone Number must be 13 digits long';
    $errflag = true;
}

if(strlen($phone) <> 13) {
    $errmsg_arr[] = 'Phone Number must be 13 digits long';
    $errflag = true;
}	

 

 

if($phone <> 13){
   echo "Phone number must be 13 digits long";
}

No, that's not it but I got it thanks

 

	if(strlen($newphone) <>13) {
	$errmsg_arr[] = 'Phone Number must be 13 digits long';
	$errflag = true;
}

if($newphone == ''){
	$errflag = false;
}
