This checks looks for assignemnts to variables using the list(...) function, where not all assigned variables are subsequently used.
list(...)
Consider the following code example.
<?php function returnThreeValues() { return array('a', 'b', 'c'); } list($a, $b, $c) = returnThreeValues(); print $a . " - " . $c;
Only the variables $a and $c are used. There was no need to assign $b.
$a
$c
$b
Instead, the list call could have been.
list($a,, $c) = returnThreeValues();
$url = Router::url($url);
return $this->_view->Html->link($title, $url, $options);
}
