使用PHP将文件删除到MySQL数据库中
问题描述：
首先，我自学PHP和MYSQL，我看到你的指南使用PHP将文件上传到MySQL数据库。这是很棒的指南和响应。
我的问题是我现在如何从上面创建的指南中删除文件，
谢谢
Hi,
First off I am self learning PHP and MYSQL, which I saw your guide on "Uploading files into a MySQL database using PHP" and this was great guide and responses that had came through.
My question is how do I now remove files from the guide that you have created above,
thanks
答
从数据库中删除它们（使用DELETE查询并传递PK）。
delete them from the database (using a DELETE query and passing the PK).
你好Dormilich，
抱歉PK是主键？
我怎么会这样做，因为我正在考虑创建list_files.php中链接的删除文件，以便在打开时我可以查看我要下载的文件或者删除。
感谢您的回复
Hi Dormilich,
Sorry is PK the primary key?
how would I go about this as I was thinking to create the delete file that is linked in the list_files.php so that when open I can then view the files that I want to download or delete.
thanks for the reply

正确。
删除文件应该这样做，从数据库中删除所选条目。
list_files.php中所需要的只是一个调用删除脚本的链接/表单，向其传递要删除的文件的ID（PK）。
correct.
the delete file should do just this, delete the chosen entry from the DB.
all you need in the list_files.php is a link/form that calls the delete script passing it the ID (PK) of the file to be deleted.
