更好列表页中一个航班.先unset删除数组中一个键值对,再追加,最后按键排序

<?php

$arr = array(
‘0‘ => array(‘item‘ => array(
‘aa‘ => ‘aaa‘,
‘bb‘ => ‘bbb‘
)),

‘1‘ => array(‘item‘ => array(
‘cc‘ => ‘ccc‘,
‘dd‘ => ‘ddd‘
)),

‘2‘ => array(‘item‘ => array(
‘ee‘ => ‘eee‘,
‘ff‘ => ‘fff‘
))
);

echo ‘<meta http-equiv="Content-type" content="text/html:charset=utf-8">‘;
echo ‘<pre>‘;

unset($arr[1]);
$arr[1] = array(
‘item‘ => array(
‘hh‘ => ‘hhh‘,
‘jj‘ => ‘jjj‘
)
);

var_dump($arr);
ksort($arr);
var_dump($arr);
