PHP開啟opcache提升代碼效能，php開啟opcache代碼

配置指令如下：

[opcache]zend_extension=opcache.soopcache.enable_cli=1;共用記憶體大小, 這個根據你們的需求可調opcache.memory_consumption=256   ;interned string的記憶體大小, 也可調opcache.interned_strings_buffer=8;最大緩衝的檔案數目opcache.max_accelerated_files=4000;60s檢查一次檔案更新opcache.revalidate_freq=60;開啟快速關閉, 開啟這個在PHP Request Shutdown的時候 會收記憶體的速度會提高opcache.fast_shutdown=1;不儲存檔案/函數的注釋opcache.save_comments=0 

實際效能對比：

下面是實際測試中沒有開啟opcache的資料：
