1.2.1393. Useless Default Argument

One of the argument has a default value, and this default value is never used. Every time the method is called, the argument is provided explicitly, rendering the default value actually useless.

<?php

function goo($a, $b = 3) {
    // do something here
}

// foo is called 3 times, and sometimes, $b is not provided.
goo(1,2);
goo(1,2);
goo(1);


function foo($a, $b = 3) {
    // do something here
}

// foo is called 3 times, and $b is always provided.
foo(1,2);
foo(1,2);
foo(1,2);
?>
