Are there any free web servers that support PHP?
free web servers
There are heaps on the net. You could use the Apache, but if you want something really small and simple to set up I would go with Abyss Web Server, which is very very small (less than 1Mb). You can download it from http://www.aprelium.com/abyssws/index.html
thanks!!!
If you meant web hosts, this lists a few:

If you mean 'web servers' then Apache is by far the most popular. Here is a list of 'installation packages' what will automagically install PHP along with a web server (usually Apache) and other modules like a database (typically MySQL)...
