Is Downloading PHP needed?

So I have been reading online on how to use PHP and I am getting the idea. But every one says to download PHP. Is this needed? I have this on my server, it;s lunix hosting:

Database Set Up and ConfigurationThe following view and edit options are available on this page:

Available or set up databases
You see all the databases set up so far, as well as the availability of additional MySQL databases.
If you have not used a database yet, please click on Set Up to enable the MySQL database.
Configuration of the MySQL database
Delete an existing database or change its password.
Disk space
See details on the used, maximum, and remaining disk space for every database created within this package.

Important MySQL Usage Information
The MySQL database may not be used for log evaluation operations, ad clicks, chat systems, banner rotations, or similar applications putting extreme loads on the database under any circumstances.
Your MySQL databases are stored behind a firewall to protect your data. You can only access each one exclusively through your server. Direct access to your MySQL databases using a home PC (external ODBC connection) cannot be established.
Please note:
The Admin function gives you unrestricted access to your MySQL databases. Any changes made using this interface cannot be rolled back. Deleting entries in forum (ex. phpBB), guestbook or similar applications should only be made using the administrative functions of the particular application.

Does this mean it is already there? Or do I need to upload it into the database?
Thanks!

this is about mysql. to see if your hosting has php, just upload a php file to see if it is parsed.

yep create a php file with this code to check your php:

<?php phpinfo() ?>


btw you can't install php on your linux hosting accpunt

Oh, I see. So I did what you said and have a whole page of info. Here's the 1st part of it.

So I guess it is there. Well then now I am confussed. What does the MYSQL have to do with it? Wait, I will go read and figure it that out, maybe I am not that far in the learning.
Thanks for your help.

That means that your host has php. Mysql is a database, php is a programming language
