Php 数组或变量在输入if/else语句时丢失值

下面是我为$list声明值的一些代码

$list['first_name']            = Request::input("first_name");
$list['last_name']             = Request::input("last_name");

当我使用dd（$list）时，它显示的值与我的

但当它进入这个if-else语句时

if($existing_customer)
{
     $customer_id            = $existing_customer->customer_id;
}
else
{
    dd($list);
    $insert_customer["first_name"]     = ($list['first_name'] == "undefined" ? "John" : ucfirst($list['first_name']));
    $insert_customer["last_name"]      = ($list['last_name'] == "undefined" ? "Doe" : ucfirst($list['last_name']));
}

这是最新的

这是我的功能照片，如果可以的话。

我真的看不出哪里出错了，因为输入if/else语句的值变为null。

为什么不将代码放在文本中？对不起，先生，我的函数有点长，但我放在文本中的代码基本上是出错的地方。。。我想选择你的代码。复制它们。将它们粘贴到编辑器中。再次在编辑器中选择你的代码。按编辑器中的{}按钮，你会看到它工作正常，没有问题：）先生，有更新，所以如果你在同一个脚本实例中进行两个调试输出，一个直接在if之前，另一个在else分支中，你会得到两个不同的输出？您能否将调试输出的确切位置编辑为上述函数的完整代码，以便我们以1:1的比例看到您正在执行的内容？
