Php 创建目录并将多个文件上载到创建的目录中

我已经挖掘了好几天的答案。如何将多个文件上载到新创建的目录。如果您查看文件\u upload.php，您将发现两个

$upload\u dir

变量。因此，让我们首先调用

$upload\u dir

作为直接文件夹，然后调用

$upload\u dir

作为make dir。简单的

因此，当我选择第一个

$upload\u dir

时，它会将所有文件直接上载到文件夹中；当我选择第二个

$upload\u dir

时，它会创建一个随机文件夹，但无法上载任何文件

我想上传多个文件到新创建的文件夹

我确实提到了这一点，但没有为我工作

index.php

<form action="file_upload.php" method="POST"
            enctype="multipart/form-data">

上传文件

选择要上载的文件：

文件\u upload.php

请帮忙

提前感谢

mkdir

返回布尔值（true或false），而不是创建的目录路径

您可能希望在

$upload\u dir

中定义路径，但不将mkdir的结果分配给它：

$upload_dir = 'C:/fileUpload/'. $rand_name .'/';

if (mkdir($upload_dir, 0777)) {
   //process images
}

---

mkdir

返回一个

布尔值

，因此分配

$upload\u dir=mkdir（…）

可能不是您希望转储$\u FILES数组以查看其结构。。。然后根据真实结构修复代码。。。老实说，我想知道，如果人们不知道自己的数据是什么样子，他们会如何编程……仅供参考，

mkdir

的第三个参数值得使用，因为它可以确保生成路径中的所有文件夹useful@LarsStegelitz我已经相应地构建了$\u文件，因此无法解决我的问题issue@ProfessorAbronsius对不起，先生。我无法理解你的答案。如果可能的话，你能给我提供更多关于这个问题的细节吗。
