Training in PHP and .net

“The struggle you're in today is developing the strength you need for tomorrow. ”
If you’re a software developer, there simply isn’t enough time in the world to learn every single technology, language and platform you might need for work, or to land a better job; at some point, you’re going to have to decide in what direction you want to expand your knowledge base.
As mentioned above, PHP is an open-source programming language primarily used for developing Web-based applications. There are a few tools out there that allow you to use it to write desktop applications, but the majority of apps written in PHP run on a Web server (most people using PHP seem to do so with an Apache server, although a few also rely on Microsoft IIS).
While .NET is built into Microsoft Windows, you can run .NET desktop applications on Linux using a free and open source product called Mono. PHP sometimes comes pre-installed on Linux, and if not, it’s quick and easy to install. But to develop with either platform, you need some free tools: for .NET, you’ll want one of the free Visual Studio Express products from Microsoft; For PHP, there are several options—one popular choice is Eclipse.
