Description
mixed
prev ( 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.
| Warning |
If the array contains empty elements then this function will
return a value which evaluates to FALSE for these elements as well
(see converting to boolean
and the type comparison tables
for more information).
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.
Example 1. Example use of prev() and friends
<?php
$transport = array('foot', 'bike', 'car', 'plane');
$mode = current($transport); // $mode = 'foot';
$mode = next($transport); // $mode = 'bike';
$mode = next($transport); // $mode = 'car';
$mode = prev($transport); // $mode = 'bike';
$mode = end($transport); // $mode = 'plane';
?>
