php数组current和next的用法，二个例子，方便大家理解current和next的使用方法。
php数组 current和next的用法
1、current取php数组当前值

$mode=current($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';
?>
2、next取php数组下一个值
<?php

$mode=current($transport);//$mode='foot';
