Description:
------------
The test script generates a Fatal error: Uncaught Error: Cannot declare
self-referencing constant 'self::FOO'
All lines of test script are required, except the last line, which is just
there to output something.
Removing any of the following eliminates the error:
namespace
second constant
constant assignment
I tested on a number on both win10 and linux(ubuntu 16.04), and a number of php
7.2 versions.
This: https://3v4l.org/3aIHb
says it works on php5.6 versions and fails in php7.0+
Test script:
---------------
<?php
namespace Waffles;
abstract class A
{
const FOO = self::FOO;
const OTHER = 0;
private $waf = self::OTHER;
}
class B extends A
{
const FOO = 'waffles';
}
$foo = new B();
echo $foo::FOO;
Expected result:
----------------
waffles
Actual result:
--------------
Fatal error: Uncaught Error: Cannot declare self-referencing constant
'self::FOO'
