PHP yii\caching Cache::add Beispiele

add() public method

Nothing will be done if the cache already contains the key.

public add ( mixed $key, mixed $value, integer $duration, yii\caching\Dependency $dependency = null ) : boolean
$key	mixed	a key identifying the value to be cached. This can be a simple string or a complex data structure consisting of factors representing the key.
$value	mixed	the value to be cached
$duration	integer	the number of seconds in which the cached value will expire. 0 means never expire.
$dependency	yii\caching\Dependency	dependency of the cached item. If the dependency changes, the corresponding value in the cache will be invalidated when it is fetched via [[get()]]. This parameter is ignored if [[serializer]] is false.
return	boolean	whether the value is successfully stored into cache
