(PECL apcu >= 4.0.0) Clears the APCu cache bool apcu_clear_cache ( void ) Clears the cache. Returns: Returns TRUE always See also: apcu_cache_info() -

(PECL apcu >= 4.0.0) Retrieves cached information from APCu's data store array apcu_cache_info ([ bool $limited = false ] ) Retrieves cached information and meta-data from APC's data store. Parameters: limited If limited is TRUE, the return value will exclude the individual list of cache entries. This is useful when trying to optimize calls for statistics gathering.

(PECL apcu >= 4.0.0) Checks if entry exists mixed apcu_exists ( mixed $keys ) Checks if one or more APCu entries exist. Parameters: keys A string, or an array of strings, that contain keys. Returns: Returns TRUE if the key exists, otherwise FALSE Or if an array was passed to keys, then an array is returned that contains all existing keys, or a

(PECL apc >= 3.1.1) Checks if current position is valid public void APCIterator::valid ( void ) Checks if the current iterator position is valid. Returns: Returns TRUE if the current iterator position is valid, otherwise FALSE. See also: APCIterator::current() - Iterator::valid() -

(PECL apc >= 3.1.1) Get total cache size public int APCIterator::getTotalSize ( void ) Gets the total cache size. Returns: The total cache size. This function is currently not documented; only its argument list is available. See also: APCIterator::getTotalCount() -

(PECL apcu >= 4.0.0) Cache a new variable in the data store bool apcu_add ( string $key, mixed $var [, int $ttl = 0 ] ) array apcu_add ( array $values [, mixed $unused = NULL [, int $ttl = 0 ]] ) Caches a variable in the data store, only if it's not already stored. Note: Unlike many other mechanisms in PHP, variables stored using apcu_add() will persist between requests (until the value is removed from the cache).

(PECL apc >= 3.1.1) Get iterator key public string APCIterator::key ( void ) Gets the current iterator key. Returns: Returns the key on success, or FALSE upon failure. See also: APCIterator::current() - Iterator::key() -

(PECL apc >= 3.1.1) Rewinds iterator public void APCIterator::rewind ( void ) Rewinds back the iterator to the first element. Returns: No value is returned. See also: APCIterator::next() - Iterator::next() -
