Php 正在尝试从第二级删除数组项

我试图查找这个，但没有找到像我这样的数组。我尝试过的任何东西都不起作用，现在我已经是第十次得到了一份简历

我在103/104处对错误进行了评论 我需要在某一点上从一个序列化的数组中获取它，因此需要进行转换（抱歉） 我试图做一个功能，可以寻找什么需要删除

注意：我还需要添加一个完整的记录，因为我也不知道如何在数组中这样做，但我可能应该问另一个问题

我查找的所有数组都没有找到我所拥有的数组，它的[0]=>作为顶级数组，当我尝试它的示例时，它并不与我拥有的数组相同。 因此在这里提出问题

感谢您的帮助下面是我的php代码

<?php

尽管您不想从函数中返回任何内容吗？
使用
$此
会抛出错误，因为您是从对象中使用它的。。
$this
的可接受用法为：

你的职能应该是：

删除
$此
将解决此错误
 我修改了我的问题-请参见底部的编辑注释-谢谢您的回答我排除了这一点并提出了问题。谢谢你在这方面的帮助我修改了帖子的问题谢谢你的回答是的，我也想知道递归的答案-以及如何返回它..再次感谢，并对混淆表示抱歉，请参阅我帖子底部的编辑说明
works now thank you
