Code Inspection: Expression is always 'null'

Reports the variables in return statements that are always null.

In the following example, the $var variable returned from within the conditional statement is always null. After the quick-fix is applied, the variable is replaced with the explicit null value.

                function getValue($var) {
                    if ($var === null) {
                        return $var;
                    }
                    return $var;
                }
            

                function getValue($var) {
                    if ($var === null) {
                        return null;
                    }
                    return $var;
                }
