1.2.268. Could Be Self

Mark arguments, return types and properties that can be set to self. This applies only to methods.

This analysis works when typehints have already been configured.

<?php

class x {
    // Accept a x object as input
    function foo(x $b) : x {
        // Returns a x object
        return $b;
    }
}

?>
