PHP开启opcache提升代码性能_php技巧

[opcache]zend_extension=opcache.soopcache.enable_cli=1;共享内存大小, 这个根据你们的需求可调opcache.memory_consumption=256   ;interned string的内存大小, 也可调opcache.interned_strings_buffer=8;最大缓存的文件数目opcache.max_accelerated_files=4000;60s检查一次文件更新opcache.revalidate_freq=60;打开快速关闭, 打开这个在PHP Request Shutdown的时候 会收内存的速度会提高opcache.fast_shutdown=1;不保存文件/函数的注释opcache.save_comments=0
