well after testing several php editors/ide here is the list:
- notepad++ simple editor with syntax highlighting and basic auto completion - free
- vs code: as an editor is great as an IDE is cumbersome: plus FREE
- phpdesigner8 IDE with intellisense, auto completion and easy to use, the problem is paid
- eclipse for php: IDE with simple intellisense and auto completion, cumbersome configuration. plus: free
- PHP STORM: IDE complete and simple to use the problem: very expensive
