$file = uploadFile2($subdirectory);

Page:

<input type="text" name="file"><br>//这是一个标签，我们要实现文件的上传，必须指定为multipart/form-data，否则服务器将不知道要干什么。

Note that

enctype="multipart/form-data"

must be added to the form. If you really don’t know how, you can Copy the file directly to the folder you want to put it, and then save the path to the database. When querying, query the file path, and spell the specified path with the file name you want to check (all your files only have different file names). You can copy the path to the browser and access it. If you can access the file description, it will be successful.
