PHP 數(shù)組current和next用法分享

    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。
