(PHP 4, PHP 5, PHP 7)
Rewind the internal array pointer
mixed prev ( array &$array )
Rewind the internal array pointer.
prev() behaves just like next(), except it rewinds the internal array pointer one place instead of advancing it.
Parameters:
array
The input array.
Returns:
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.
Notes:
You won't be able to distinguish the beginning of an array from a boolean FALSE element. To properly traverse an array which may contain FALSE elements, see the each() function.
Examples:
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';
?>
