　 Analysis of php file download processing method

This article mainly introduces the PHP file download processing method. It analyzes the common PHP file download processing techniques with examples. It has certain reference value. Friends in need can refer to it

The example in this article describes how to download php files. Share it with everyone for your reference. The specific analysis is as follows:

PHP can handle file downloads under various conditions. Let’s take a look at the following example:

　?

1 2 3 4 5

header("Content-Type: application/force-download"); header("Content-Disposition: attachment; filename=testname.jpg"); readfile("images/test.jpg"); ?>

4

5

header("Content-Type: application/force-download");

1 2 3 4

header("Content-Disposition: attachment; filename=testname.jpg");

readfile("images/test.jpg");

?>

Analysis of the above code:

The first line of code is forced download; The second line of code is to assign a name to the downloaded content; The third line of code is to read the downloaded content into the file. I have always thought that it is impossible to download multiple files at the same time in one page, because after the first header of PHP sends the download information, it cannot be sent again. Today I finally know a solution, using iframe. 　?
