| $key | mixed | 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().) If $key is an array set Names in key, variables in value |
| $var | mixed | The variable to store If $key is an array, this parameter is unused and set to NULL |
| $ttl | integer | 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.). |
