apc_store
(PECL apc:3.0.0-3.0.9)
apc_store — Cache a variable in the data store
說明
Note: Unlike many other mechanisms in PHP, variables stored using apc_store() will persist between requests (until the value is removed from the cache).
參數
- key
-
Store the variable using this name. key s are cache-unique, so storing a second value with the same key will overwrite the original value.
- var
-
The variable to store
- ttl
-
Time To Live; store var in the cache for ttl seconds. After the ttl has passed, the stored variable will be expunged from the cache (on the next request). If no ttl is supplied (or if the ttl is 0), the value will persist until it is removed from the cache manually, or otherwise fails to exist in the cache (clear, restart, etc.).
Return值
如果成功則回傳 TRUE，失敗則回傳 FALSE。
