What harm can virus sites that contain malicious PHP code cause? What is an example of a piece of PHP code that could potentially harm your computer or steal information? I know that most if not all client-side code cannot cause any harm, but how about the server-side code, what harm could it cause?

It all comes down to the credentials that .PHP virus is running with on the server. If the apache2 process running that PHP code is running as www-root, the damage that this script can do goes to the extent of what www-root can access, which would typically mean all of the /var/www/ folder. To fully understand this question, one needs to understand how linux works, if the web server is running under linux, to fully understand the extent of the possible damage. If it's running under Windows, it would be the same thing, only the damage would be to the extent of what the owner of the process is able to use the machine's resources for.
