Subject: Re: [PHP-DEV] Please confirm behaviour of ZEND_ACC_STATIC
From: helly@php.net (Marcus Boerger)

Hello l0t3k,

never ever mix static and non static methods!
The only reason this is possible is for having BC for old
bullshit concepts. Apart from that use ZEND_ACC_ALLOW_STATIC
if you really want that behavior but before you do think
twice and again and then again if there is no correct way...
