I'm customsing and developing some PHP-based applications (including Moodle). As you know, a good IDE helps use write productive codes and reduce much our time (A programmer is only as good as his tools).
Personally, I think PHP IDEs are rather limited in comparison with other IDEs of other languages such as Java (JBuilder, Java Studio Creator, etc), .NET(Visual Studio Net).
I tested some PHP-IDEs: PHP Edit, DevPHP, Dreamweaver, PHPEclipse. PHPEdit seems better but it's a commercial product.
Could you share your experiences of PHP IDEs? (I guess many Moodlers know good PHP IDEs because Moodle is PHP-based)
