Yesterday, InfoWorld posted an in-depth review of eight PHP-capable IDE’s. Eclipse with PDT, Netbeans, Zend Studio, NuSphere PhpED, and ActiveState Komodo all get “very good” marks. Of these, Eclipse and Netbeans are free, which is always a bonus. If you’re looking for a new IDE for your PHP development, do read this article.
Personally, I use a text editor for my PHP development (TextMate for Mac OS X). But I have used Eclipse quite a bit, just not for PHP. Eclipse is a standard foundation for lots of IDEs, like Flex Builder/Flash Builder and Aptana Studio. I’ve used Netbeans for Ruby development. Both Netbeans and Eclipse are quite good and extremely extendable, but not as user-friendly as some commercial products, in my opinion. I never really took to Zend Studio, for no particular reason. Maybe the price! I did use NuSphere PhpEd for a while (I did some consulting work for that company) and it seemed to be a very likable solution, but it only runs on Windows, which rules it out for me.
