Are you sure the assignment to
$ipaddress is correct as get_client_ip2() seems to always return null .
This check looks for function or method calls that always return null and whose return value is assigned to a variable. class A

$a = new A();
$object = $a->getObject();
The method The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. ![]() |
