Caches a variable in the data store, only if it's not already stored

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

@since  3.0.13
@param  mixed $key 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
@param  mixed $var The variable to store
If $key is an array, this parameter is unused and set to NULL
@param  int $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.).
@return mixed
Caches a variable in the data store only if it s not already stored
