Laufzeit-Konfiguration

Das Verhalten dieser Funktionen wirddurch Einstellungen in der php.ini beeinflusst.

The following table lists and explains the configuration settings provided by the WinCache extension:

Weitere Details und die Definitionen derPHP_INI_*-Konstanten finden Sie im php.php-dokumentation-ini Einstellungen.

Hier eine kurze Erklärung derKonfigurationsoptionen:

wincache.fcenabled boolean

Enables or disables the file cache functionality.

wincache.fcenabledfilter string

Defines a comma-separated list of IIS web site identifiers where file cache should be enabled or disabled. This setting works in conjunction with wincache.fcenabled: if wincache.fcenabled is set to 1, then the sites listed in the wincache.fcenabledfilter will have the file cache turned off; if wincache.fcenabled is set to 0, then the sites listed in the wincache.fcenabledfilter will have the file cache turned on.

wincache.fcachesize integer

Defines the maximum memory size (in megabytes) that is allocated for the file cache. If the total size of all the cached files exceeds the value specified in this setting, then most stale files will be removed from the file cache.

wincache.maxfilesize integer

Defines the maximum allowed size (in kilobytes) for a single file to be cached. If a file size exceeds the specified value, the file will not be cached. This setting applies to the file cache only.

wincache.ocenabled boolean

Enables or disables the opcode cache functionality

wincache.ocenabledfilter string

Defines a comma-separated list of IIS web site identifiers where opcode cache should be enabled or disabled. This setting works in conjunction with wincache.ocenabled: if wincache.ocenabled is set to 1, then the sites listed in the wincache.ocenabledfilter will have the opcode cache turned off; if wincache.ocenabled is set to 0, then the sites listed in the wincache.ocenabledfilter will have the opcode cache turned on.

wincache.ocachesize integer

Defines the maximum memory size (in megabytes) that is allocated for the opcode cache. If the cached opcode size exceeds the specified value, then most stale opcode will be removed from the cache. Note that the opcode cache size must be at least 3 times bigger than file cache size. If that is not the case the opcode cache size will be automatically increased.

wincache.filecount integer

Defines how many files are expected to be cached by the extension, so that appropriate memory size is allocated at the startup time. If the number of files exceeds the specified value, the WinCache will re-allocate more memory as needed.

wincache.chkinterval integer

Defines how often (in seconds) the extension checks for file changes in order to refresh the cache. Setting it to 0 will disable the refreshing of the cache. The file changes will not be reflected in the cache unless the cache entry for that file is removed by scavenger or IIS application pool is recycled or wincache_refresh_if_changed function is called.

wincache.ttlmax integer

Defines the maximum time to live (in seconds) for a cached entry without being used. Setting it to 0 will disable the cache scavenger, so the cached entries will never be removed from the cache during the lifetime of the IIS worker process.

wincache.enablecli boolean

Defines if caching is enabled when PHP is running in command line (CLI) mode.

wincache.ignorelist string

Defines a list of files that should not be cached by the extension. The files list is specified by using file names only, separated by the pipe symbol – "|".

Beispiel #1 wincache.ignorelist example

wincache.ignorelist = "index.php|misc.php|admin.php"

wincache.namesalt boolean

Defines a string that will be used when naming the extension specific objects that are stored in shared memory. This is used to avoid conflicts that may be caused if other applications within an IIS worker process tries to access shared memory.
