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 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.
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';
?> |
