我不能给你整个代码，但可以告诉你正确的轨道。
使用
例如。
for pdf， header（''Content-type：application / pdf''）;
for jpg image header（''Content-type：image / jpeg''）;
I can''t give you the whole code, but can show you the right track.
Use header in the starting of the PHP page and then print the required data from the database afterwards.
Eg.
for pdf, header(''Content-type: application/pdf'');
for jpg image header(''Content-type: image/jpeg'');
我已经阅读了那本手册，但我对它有疑问。
就像当用户注册时他存储了描述自己的图像或文字文档。因此，当用户查看另一个用户的个人资料时，应该给他一个选项来下载该特定用户上传的word文档。它从用户变为用户。它们在数据库中与用户名相关联。如何在标题中每次更改文件名，因为它对所有用户都是不同的。
I have gone through that manual but i had a doubt in it.
Like when a user registers he stores a image or a word document describing himself. So when a user views the profile of another user then he should be given an option to download the word document uploaded by that particular user. It changs from user to user. They are associated in the datbase with the name of the user. How can the filename be changed everytime in the header because it will be different for all the users.

为此，你需要让这样的逻辑运行，如果你打开页面 get_file.php？file = abc.doc ，它应该打开 abc.doc 。
看看此帖子。这仅适用于图像类型，但它可能对您有所帮助。
问候，

For that you need to make a logic running behind like this, that if you open page get_file.php?file=abc.doc, it should open abc.doc.
Look at this post. This is only for image type, but it may help you.
