PHP 數組current和next用法分享

 本文這裡通過示例給大家簡單對比分析了PHP 數組current和next的用法，雖然示例很簡單，但是對於我們理解current和next非常有幫助，這裡推薦給大家。

   

1.current

 

代碼如下:
<?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

 

代碼如下:
<?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';
?>

 

示例很簡單，但是卻很實用，希望小伙伴們能夠喜歡。
