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
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';
?>
2.next
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';
?>
示例很简单,但是却很实用,希望小伙伴们能够喜欢。
