How to use php to directly download PDF files from a browser

This article describes how to allow users to open pdf files instead of directly browsing in the browser, but directly downloading the pdf file to a computer. some browsers have installed the pdf Open Program and associate it with the browser, therefore, when you write the pdf path directly, open the pdf instead of downloading it. next I will explain that if you want them to just download, not browse.

Create a php file

The code is as follows:
$ File = $ _ GET ['file'];
$ Arr = explode ('/', $ file );
Header ('content-type: application/pdf ');
Header ('content-Disposition: attachment; filename = "'. array_pop ($ arr ).'"');
Readfile (file );
?>


Add the code to convert the pdf path into a language recognized by the browser and tell the browser
Column/upload. php? File =/aa/aa.pdf
In this way, everything can be downloaded instead of being opened.
