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.
| Avertisment |
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().
