apc_store (PECL) apc_store --
Cache a variable in the data store
说明bool apc_store ( string key, mixed var [, int ttl] ) 注:
Unlike many other mechanisms in PHP, variables stored using
apc_store() will persist between requests (until the
value is removed from the cache).
参数
- key
Store the variable using this name. keys 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.).
返回值
如果成功则返回 TRUE,失败则返回 FALSE。
