(no version information, might be only in CVS)apc_add -- Cache a variable in the data store (only if it's not stored)
Popisbool apc_add ( string key, mixed var [, int ttl] )
Poznámka: Unlike many other mechanisms in PHP, variables stored using apc_add() will persist between requests (until the value is removed from the cache).
Store the variable using this name.
keys are cache-unique, so attempting to use apc_add() to store data with a key that already exists will not overwrite the existing data, and will instead return FALSE. (This is the only difference between apc_add() and apc_store().)
The variable to store
Time To Live; store
varin the cache for
ttlseconds. After the
ttlhas passed, the stored variable will be expunged from the cache (on the next request). If no
ttlis supplied (or if the
ttlis 0), the value will persist until it is removed from the cache manually, or otherwise fails to exist in the cache (clear, restart, etc.).
