本文这里通过示例给大家简单对比分析了PHP 数组current和next的用法,虽然示例很简单,但是对于我们理解current和next非常有帮助,这里推荐给大家。

1.current

<?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';
 ?>

2.next

<?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';
 ?>

示例很简单,但是却很实用,希望小伙伴们能够喜欢。
