Modification of the array returned from function by value won't have any effect

Reports call to a function that returns array by value, which makes the assignment operation non-working. Return by reference shall be used instead.

For example:

<?php class A { private $values = []; public function getValues() { return $this->values; } } $config = new A(); $config->getValues()['a'] = 'a';
