prev -- Rewind the internal array pointer
Description
mixed prev (array array)
Returns the array element in the previous place that's pointed by the internal array
pointer, or FALSE if there are no more elements.
| Warning |
|
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.
See also current(), end(), next(), and reset().
