1.2.1256. Undefined Insteadof¶

Insteadof tries to replace a method with another, but it doesn’t exists. This happens when the replacing class is refactored, and some of its definition are dropped.

Insteadof may replace a non-existing method with an existing one, but not the contrary.

This error is not linted : it only appears at execution time.

<?php

trait A {
    function C (){}
}

trait B {
    function C (){}
}

class Talker {
    use A, B {
        B::C insteadof A;
        B::D insteadof A;
    }
}

new Talker();
?>
