代码如下:
<?php
$transport = array('foot', 'bike', 'car', 'plane');
$mode = current($transport); //$mode = 'foot';
$mode = next($transport); // $mode ='bike';
$mode = current($transport); //$mode = 'bike';
$mode = prev($transport); // $mode ='foot';
$mode = end($transport); // $mode ='plane';
$mode = current($transport); //$mode = 'plane';
?>

代码如下:
<?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';
