ParamsReturnSource
Performs an atomic decrement operation on specified numeric cache item.
Note that if the value of the specified key is *not* an integer, the decrement operation will have no effect whatsoever. Redis chooses to not typecast values to integers when performing an atomic decrement operation.

Parameters

  • string $key Key of numeric cache item to decrement
  • integer $offset Offset to decrement - defaults to 1.

Returns

closure Function returning item's new value on successful decrement, else `false`

		};
