A question about php_apc

[Apc] apc. enabled = 1apc. shm_segments = 1apc. shm_size = 64Mapc. optimization = 1apc. num_files_hint = 1000apc. ttl = 0apc. gc_ttl = 3600apc. cache_by_default = Onapc.

[Apc]
Apc. enabled = 1
Apc. shm_segments = 1
Apc. shm_size = 64 M
Apc. optimization = 1
Apc. num_files_hint = 1000
Apc. ttl = 0
Apc. gc_ttl = 3600
Apc. cache_by_default = On
Apc. slam_defense = 0
Apc. file_update_protection = 2
Apc. enable_cli = 0
Apc. stat = 0

In this case, the program cannot be refreshed. if you refresh it once, an error occurs:

It mainly indicates that the include_once part has an error:

Warning: include_once (D: \ wamp \ www \ inventory): failed to open stream: Permission denied in D: \ wamp \ www \ inventory \ logview. php on line 61

Warning: include_once (): Failed opening ''for future Sion (include_path = '.; d:/wamp/www ') in D: \ wamp \ www \ inventory \ logview. php on line 61

It is very strange that the windows \ temp permission and the d: \ wamp \ www permission are set, but an error is still reported,
If you comment out extension = php_apc.dll, it will be okay. if you do not know why, record it and find the cause before updating it.
