apcu_store — Cache a variable in the data store

说锟斤拷

apcu_store ( string $key , mixed $var [, int $ttl = 0 ] ) : bool
apcu_store ( array $values [, mixed $unused = NULL [, int $ttl = 0 ]] ) : array

Cache a variable in the data store.

Note: Unlike many other mechanisms in PHP, variables stored using apcu_store() will persist between requests (until the value is removed from the cache).

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.).

values

Names in key, variables in value.
