How can I insert an item in the middle of an object in PHP?

如果我有一个像下面这样的stdClass对象，它有三个非数字键的数组，在我的帐户和设置之间插入另一个项目的最好方法是什么?

[menu1] => stdClass Object
    (
        [my-account] => Array
            (
                [title] => 'My Account'
                )
        [settings] => Array
            (
                [title] => 'Settings'
                )
        [payments] => Array
            (
                [title] => 'Payments'
                )
)

为此创建您自己的类，其中包含添加和删除项及其属性的函数。然后使用提供的一些函数，如@genesis。

没有这样的函数。你必须自己动手重建你的对象

<?php
function insert_after($var, $key, $value, $after){
    $new_object = array();
    foreach((array) $var as $k => $v){
       $new_object[$k] = $v;
       if ($after == $k){
           $new_object[$key] = $value;
       }
    }
    $new_object = (object) $new_object;
    return $new_object;
}
$var = insert_after($var, 'new dummy var between', array('title' => 'value'), 'my-account');

添加条目，然后删除并重新添加后面需要的条目:

$menu1->newitem = array('title'=>'Title');
$settings = $menu1->settings;
unset($menu1->settings);
$menu1->settings = $settings;
unset($settings);
unset($menu1->payments);
$menu1->payments = $payments;
unset($payments);
