Zend Engine 2 Opcodes
Вернуться к: Ядро PHP: Руководство хакера
Содержание
When parsing PHP files, Zend Engine 2 generates a series of operation codes, commonly known as "opcodes", representing the function of the code. This part of the manual details those opcodes and their behaviour.
Opcodes may be dumped for a given PHP file using the vld extension (see » http://pecl.php.net/package/vld).
