Cache a variable in the data store - Справочник: PHP5.4

Описание

bool apc_store ( string $key , mixed $var [, int $ttl = 0 ] )

array apc_store ( array $values [, mixed $unused [, int $ttl = 0 ]] )

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).

Список параметров

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.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки. Second syntax returns array with error keys.
