PHP 클래스 Zephir\Passes\LocalContextPass

This pass tries to check whether variables only do exist in the local context of the method block or if they're used externally which will unallow variables to be placed in the stack This pass also tracks the number of initializations a variable may have, this allows to mark variables as read-only after their last initialization. The number of mutations is relative, since assignments inside cycles/loops may perform a n-number of mutations 파일 보기 프로젝트 열기: phalcon/zephir 1 사용 예제들
