PHP: Hypertext Preprocessor (PHP) is a free, highly popular, open source scripting language. PHP scripts are executed on the server.

Just a short list of what PHP is capable of:
- Generating dynamic page content
- Creating, opening, reading, writing, deleting, and closing files on the server
- Collecting form data
- Adding, deleting, and modifying information stored in your database
- controlling user-access
- encrypting data
- and much more!

This was taken directly from the PHP tutorial here in Sololearn.
