Tools to Develop websites in Linux

Here I am going to mention the basic and some pretty good tools to develop websites...
Of course using Linux and free software :P.

1. First program I use is XAMPP which includes a web server (APACHE), Database System (MySQL) and includes PHP. Besides this capabilities of this program it provides with pretty good tools to manage a web based system, like PhpMyAdmin to manage MySQL with a pretty nice and easy to use GUI.
   
2. Aptana is a free IDE to manage a website, to make easier to understand it is similar to Dreamweav....something, tough It has some nicer features despite that everything runs pretty much faster than Dream..something. And It is freeeeeeee.
3. To develop and debug sites easier I recommend Firefox web browser with the some nice add-ons like firebug, web developer, css viewer and colorzilla are pretty good tools to manage, design and debug your website.

Instructions to install each of this are on their websites, no trouble to get this up and running.

Good Luck, I hope this is helpful.
And Tutorials for PHP, I rather Lynda.com video tutorials, they are great!!!
