Php file download processing method analysis

This article mainly introduces the php file download processing method. The example analyzes common php processing skills for file download, which has some reference value, for more information about how to download php files, see the following example. Share it with you for your reference. The specific analysis is as follows:

Php can process file downloads with multiple conditions. let's take a look at the following example:

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

Analyze the code above:

The first line of code is forced download;
The second line of code specifies a name for the downloaded content;
The third line of code is to read the downloaded content into the file.

I always thought it was impossible to download multiple files on a page at the same time, because php cannot send the download information after sending the first header.
Today, I finally learned a solution using iframe.

You can also use js to generate iframe
