It seems like
$port can also be of type string ; however, parameter $port of mysqli::__construct() does only seem to accept integer , maybe add an additional type check?

Are you sure the usage of
mysqli_free_result($r) is correct as it seems to always return null .
This check looks for function or method calls that always return null and whose return value is used. class A
{
function getObject()
{
return null;
}
}
$a = new A();
if ($a->getObject()) {
The method The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes.
