hello a friend of mind ask something about php editor for his companion on coding.
PHP Editor that able to trace dependency of all function in a file with models/controllers or another part of a framework (or something we had code).
Basicly we use notepad++ but seeking another alternative.
I used Eclipse PDT, Aptana, Netbeans, and Komodo. For Web development (at least my style: PHP, Python, Perl, HTML, JavaScript, Ruby, CSS, all the goodies) nothing has touched Komodo IDE. There is a free/open source version called Open Komodo that, unfortunately, is not as feature complete as Komodo IDE but still great.
It runs on Windows, Linux, and Mac (which is a plus since I use all three at times), is completely extendible through plugins, has source code repository features, file transfer features (s/ftp, scp, etc) and so much more. What it really wins on is polish (things like multi-language/library code auto complete).
