Code Inspection: Unnecessary 'else' branch

Reports the else branches in if statements whose bodies always execute a terminating statement such as return or throw. Such branches are redundant and can be safely omitted.

In the following example, if the condition evaluates to true, $a is returned and the function execution is immediately terminated. The statement return $b; can only be reached if the condition evaluates to false, so after the quick-fix is applied, the code is simplified by unwrapping the else branch.

function returnGreater($a, $b) { if ($a >= $b) { return $a; } else { return $b; } }
function returnGreater($a, $b) { if ($a >= $b) { return $a; } return $b; }
