This document summarizes the 6th Kansai PHP Study meeting. The meeting covered installing PHP 5.5 beta4, using the Zend OPcache for opcode caching and optimization, benchmarking a CakePHP app with and without OPcache, and briefly discussed APCu and Yac for user data caching. Zend OPcache provides opcode caching and optimization in PHP 5.5 core but requires configuration in php.ini, and user data caching requires a separate extension. The benchmark showed a 6x performance improvement for the CakePHP app when enabling OPcache.
