本文這里通過(guò)示例給大家簡(jiǎn)單對(duì)比分析了PHP 數(shù)組current和next的用法，雖然示例很簡(jiǎn)單，但是對(duì)于我們理解current和next非常有幫助，這里推薦給大家。

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(jiǎn)單，但是卻很實(shí)用，希望小伙伴們能夠喜歡。
