Bluefish is a powerful text editor aimed towards developers with features such as syntax highlighting, indentation, support for projects, auto-completion and more.
We can do PHP programming by any text editor, such as vi and nano. However, a Integrated Development Environment (IDE) is good for debugging. For IDE, I choose EasyEclipse for LAMP and it is not required to install. Download it and double click it to run. However, we should install some server programs and do some configuration before using it.
