php 数组current和next用法

1.current 当前数组

<?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 下一个数组

<?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';?>
