prev
Rewind the internal array pointer
Description
mixedprev
array&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.
If the array contains empty elements then this function will
return &false; for these elements as well.
To properly traverse an array which may contain empty elements
see the each function.
prev behaves just like
next, except it rewinds the internal array
pointer one place instead of advancing it.
