1.2.1288. 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();
?>
