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';
?>
