setAdapter ( |
| public apcu_add ( mixed $key, mixed $var = null, integer $ttl ) : mixed | ||
| $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 apcu_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.). |
| return | mixed | |
| public apcu_cache_info ( boolean $limited = false ) : boolean | ||
| $limited | boolean | 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. |
| return | boolean | Array of cached data (and meta-data) or FALSE on failure |
| public apcu_clear_cache ( ) : boolean | ||
| return | boolean | Always returns true |
| public apcu_dec ( string $key, integer $step = 1, stdClass $ref = false ) : mixed | ||
| $key | string | The key of the value being decreased. |
| $step | integer | The step, or value to decrease. |
| $ref | stdClass | success is set to TRUE in success and FALSE in failure |
| return | mixed | Returns the current value of key's value on success, or FALSE on failure |
| public apcu_delete ( mixed $key ) : mixed | ||
| $key | mixed | The key used to store the value (with apcu_store()). |
| return | mixed | Returns TRUE on success or FALSE on failure. |
| public apcu_exists ( mixed $keys ) : mixed | ||
| $keys | mixed | A string, or an array of strings, that contain keys. |
| return | mixed | 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 an empty array if none exist. |
| public apcu_fetch ( mixed $key, stdClass $ref = false ) : mixed | ||
| $key | mixed | The key used to store the value (with apcu_store()). If an array is passed then each element is fetched and returned. |
| $ref | stdClass | success is set to TRUE in success and FALSE in failure |
| return | mixed | The stored variable or array of variables on success; FALSE on failure |
| public apcu_inc ( string $key, integer $step = 1, stdClass $ref = false ) : mixed | ||
| $key | string | The key of the value being increased. |
| $step | integer | The step, or value to increased. |
| $ref | stdClass | success is set to TRUE in success and FALSE in failure |
| return | mixed | Returns the current value of key's value on success, or FALSE on failure |
| public apcu_sma_info ( boolean $limited = false ) : boolean | ||
| $limited | boolean | When set to FALSE (default) apcu_sma_info() will return a detailed information about each segment. |
| return | boolean | Array of Shared Memory Allocation data; FALSE on failure |
| public apcu_store ( mixed $key, mixed $var = null, integer $ttl ) : boolean | ||
| $key | mixed | Store the variable using this name. keys are cache-unique, so storing a second value with the same key will overwrite the original value. 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.). |
| return | boolean | Returns TRUE on success or FALSE on failure. Second syntax returns array with error keys. |
