1.2.491. Functions In Loop Calls

The following functions call each-other in a loop fashion : A -> B -> A.

When those functions have no other interaction, the code is useless and should be dropped.

Loops of size 2, 3 and 4 function are supported by this analyzer.

<?php

function foo1($a) {
    if ($a < 1000) {
        return foo2($a + 1);
    }
    return $a;
}

function foo2($a) {
    if ($a < 1000) {
        return foo1($a + 1);
    }
    return $a;
}

// if foo1 nor foo2 are called, then this is dead code.
// if foo1 or foo2 are called, this recursive call should be investigated.

?>

1.2.491.1. Suggestions

• Drop all the functions in the loop, as they are dead code
