Subject: Added E_STRICT warning in case of calling non-static method from incompatible context... 
X-Git-Tag: php-5.1.3RC2~106
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6f76b17079a709415195a7c27607cd52d039d7c3;p=php

Added E_STRICT warning in case of calling non-static method from incompatible context (this feature is staying for BC with php-4).
