1.2.1297. Unused Functions¶

The functions below are unused. They look like dead code.

Recursive functions, level 1, are detected : they are only reported when a call from outside the function is made. Recursive functions calls of higher level (A calls B calls A) are not handled.

<?php

function used() {}
// The 'unused' function is defined but never called
function unused() {}

// The 'used' function is called at least once
used();

?>
