decrement() public method

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.
public decrement ( string $key, integer $offset = 1 ) : integer | boolean
$key string Key of numeric cache item to decrement.
$offset integer Offset to decrement - defaults to `1`.
return integer | boolean The item's new value on successful decrement, else `false`.
