Submitted: 2015-02-19 21:00 UTC Modified: 2020-03-03 11:11 UTC

Status: Closed Package: Scripting Engine problem
PHP Version: 5.6.5 OS: n/a
Private report: No CVE-ID: None

Description:
------------
It reports that the non-renamed function has not been implemented, even when it has. eg http://3v4l.org/vDEP9#v5411

Test script:
---------------
<?php

trait Foo {
    abstract public function doStuff();
    
    public function main() {
        $this->doStuff();
    }
}

class Bar {
    use Foo {
        Foo::doStuff as doOtherStuff;
    }
    
    public function doStuff() {
        var_dump(__FUNCTION__);
    }
}

$b = new Bar();
$b->main();

Expected result:
----------------
Complaint about doOtherStuff not being implemented.

Actual result:
--------------
Fatal error: Class Bar contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Bar::doStuff) in /in/vDEP9 on line 19
