(PECL apc >= 3.1.1) Move pointer to next item public void APCIterator::next ( void ) Moves the iterator pointer to the next element. Returns: Returns TRUE on success or FALSE on failure. See also: APCIterator::current() - APCIterator::rewind() - Iterator:

(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() -

(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 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 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) Updates an old value with a new value bool apcu_cas ( string $key, int $old, int $new ) apcu_cas() updates an already existing integer value if the old parameter matches the currently stored value with the value of the new parameter. Parameters: key The key of the value being updated. old The old value (the value

(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) Decrease a stored number int apcu_dec ( string $key [, int $step = 1 [, bool &$success ]] ) Decreases a stored integer value. Parameters: key The key of the value being decreased. step The step, or value to decrease. success Optionally pass the success or fail boolean valu

(PECL apcu >= 4.0.0) Removes a stored variable from the cache mixed apcu_delete ( string $key ) Removes a stored variable from the cache. Parameters: key The key used to store the value (with apcu_store()). Returns: Returns TRUE on success or FALSE on failure. Examples: A apcu_de

(PECL apcu >= 5.1.0) Atomically fetch or generate a cache entry mixed apcu_entry ( string $key, callable $generator [, int $ttl = 0 ] ) Atomically attempts to find key in the cache, if it cannot be found generator is called, passing key as the only argument. The return value of the call is then cached with the optionally specified ttl, and returned. Note: When control enters apcu_entry() the lock for the cache is acq
