APC配置

1.下载php_apc.dll 到PHP的ext目录下
2.修改php.ini 添加extension=php_apc.dll
在php.ini尾部添加配置项

;这里的问题,这里修改了默认内存配置WIN7下出错,不知道大家遇到没的?
;apc.shm_size=”128″
; apc.ttl=7200
; apc.user_ttl=7200
; 修正參數
apc.ttl=”300″
apc.user_ttl=”300″
apc.num_files_hint=”1024″
apc.mmap_file_mask=”E:/Wamp/tmp/apc.XXXXXX”
apc.enable_cli=”1″
3.重新启动apache服务器,查看phpinfo中是否有apc的配置项目,有的话就配置成功了.
