I want to develop a web-based employee management system for small and medium-sized enterprises? I wrote it in PHP, but what does my programming tool use? I have never touched on PHP before and have some c ++ and java basics.
My development environment is AppServ (MysQL + APACHE + PHP)
But what is the use of my writing tools? I have learned some dreamweaver before, and I want to write with dreamweaver cs5, but it is said that dreamweaver cs5 is static, I need to write some basic enterprise employee information management. can this be achieved?
If you cannot practice, use EPP or zend. what is their free version?

You can install a php plug-in Eclipse. you can download an open-source CMS or something based on your needs. the database and other components are encapsulated and convenient for use.

It is recommended that editplus3.0 and sublime text2 be used for consideration. it is mainly small and practical, and easier to use than ZendStudio.
