apcu_add

PECL apcu >= 4.0.0
apcu_add - Cache a new variable in the data store
Manual
Code Examples

apcu_add( string$key, mixed$var, [int$ttl = 0] ): bool
arrayapcu_add arrayvalues mixedunusedNULL intttl0

Parameters

key

Store the variable using this name. keys are cache-unique, so attempting to use apcu_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 apcu_store.)

var

The variable to store

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.).

values

Names in key, variables in value.

Return Values

Returns TRUE if something has effectively been added into the cache, FALSE otherwise. Second syntax returns array with error keys.
