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'; ?>
