You can make money with proxy and CPA's.
This is how most of us do.
I'd say most people/corporations that use proxies do not make direct money with them.
They require proxies to do their online marketing or provide their online services and the results make money.
I guess Glype is way better than php.
When I did proxies, I did adsense.
You really do not make much to be honest.
If you want your proxy to live longer, do your best to track down and block websense from scanning your site on a IP level.
Judging from my logs, no one used them to shop, just to hit game sites and facebook.
Be sure to block most foreign countries or you will get ppl burning up your bandwidth looking at porn and not clicking on ads.
PHProxy is a web HTTP proxy programmed in PHP meant to bypass firewalls and access otherwise inaccessible resources (i.e. blocked websites). If the server this script is run on can access a resource, so can you!

Glype proxy script is a free-to-use, web-based proxy script written in PHP. Similar to a typical proxy server, a web-proxy script downloads requested web pages and files and forwards them back to the user. The service is provided by a web page itself, which allows instant access to the proxy without editing your browser connection settings.
Web proxies are commonly used for anonymous browsing and bypassing censorship restrictions. There is a huge market for these sites and glype proxy allows webmasters to quickly and easily set up their own proxy sites.
