The purpose is to download the dumped `backup.sql` file after running the sql dumping script (from PHP). Normally, the dumped `.sql` file is outputted (written) on the server. Then when i make a href link to that file like `<a href="backup.sql">Download File</a>`, the file is opening inside the browser on clicking, instead of being downloading.

* i just want to make a simple **HREF LINK** (to such a text file) which show up with "**Save as..**" dialog on simple **Left Click**.

How it could be done?
