Today almost every web hosting provider offers support for PHP. However if you do not know for sure if your web host offers PHP, there is very easy way to find out.

With your favorite text editor (such as Notepad) create a new document then copy and paste following line of code into the document you have just created:

<?php phpinfo(); ?>
 

Save the file and name it phpinfo.php and upload it via FTP to the root for your domain. Then point your browser to that file (should be something like www.yourdomain.com/phpinfo.php).

If your web host offers PHP your browser should open a page that will tell you the version of PHP as well as some configuration info.

If your browser opens a blank page your web host may not be offering support for PHP or it is not enable for your particular account. You should then call your web hosting provider to find out for sure.
