Here are some of the things I use every day as a web developer. Click on any one of them to find out why I use them.
Netbeans - IDE
I have been threw lots of editors and so far Netbeans has stuck. It provides every thing I'm looking for in an IDE and its free. It has support for PHP, LESS, CSS and all those other fun things I work with.
Mercurial - DVCS
I really enjoy Mercurials work flow and named branching.
Laravel - PHP Framework
I used to use codeigniter and while it is a very good framework, I feel that Laravel is even more powerful and provides a faster turn around on projects.
