Rewind the internal array pointer.
prev behaves just like next, except it rewinds the internal array pointer one place instead of advancing it.
The input array.
Returns the array value in the previous place that's pointed to by the internal array pointer, or false if there are no more elements.
This function may return Boolean false, but may also return a non-Boolean value which evaluates to false. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.
The beginning of an array is indistinguishable from a bool false element. To make the distinction, check that the key of the prev element is not null.
|8.1.0||Calling this function on objects is deprecated. Either use get_mangled_object_vars on the object first, or use ArrayIterator.|
