apc_store — Cache a variable in the data store

Cache a variable in the data store.
Замечание: Unlike many other mechanisms in PHP, variables stored using apc_store() will persist between requests (until the value is removed from the cache).

var -

ttl -

varin the cache forttlseconds. After thettlhas passed, the stored variable will be expunged from the cache (on the next request).

values -
Names in key, variables in value.
