PHP 數組函數current與next用法分享

本文這裡透過範例給大家簡單對比分析了PHP 陣列current和next的用法，雖然範例很簡單，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

<?php
$transport = array(&#39;foot&#39;, &#39;bike&#39;, &#39;car&#39;, &#39;plane&#39;);
$mode = current($transport); //$mode = &#39;foot&#39;;
$mode = next($transport); // $mode =&#39;bike&#39;;
$mode = current($transport); //$mode = &#39;bike&#39;;
$mode = prev($transport); // $mode =&#39;foot&#39;;
$mode = end($transport); // $mode =&#39;plane&#39;;
$mode = current($transport); //$mode = &#39;plane&#39;;
?>

2.next

<?php
$transport = array(&#39;foot&#39;, &#39;bike&#39;, &#39;car&#39;, &#39;plane&#39;);
$mode = current($transport); //$mode = &#39;foot&#39;;
$mode = next($transport); // $mode =&#39;bike&#39;;
$mode = next($transport); // $mode =&#39;car&#39;;
$mode = prev($transport); // $mode =&#39;bike&#39;;
$mode = end($transport); // $mode =&#39;plane&#39;;
?>

範例很簡單，但是卻很實用，希望小夥伴們能夠喜歡。
