I’ve been contacted a couple of times now by the people behind CodeLobster, a PHP-centric IDE, in the hopes that I’d review/mention CodeLobster on this site. Now, CodeLobster only runs on Windows, which means I haven’t, and probably won’t, use it myself (I primarily use a Mac, only using Windows for testing purposes), but I have no problems mentioning products and sites here that I don’t personally use, because such things may still be of use to you (you, whoever you are, presumably are a separate entity with your own interests, needs, etc., and are statistically more likely to be running Windows). Anyway…
So, CodeLobster is an IDE for PHP that runs on Windows. It’s available in both a free and “professional” version, the professional version costing $100 (US). The free version comes with an HTML editor and inspector, a CSS editor, a JavaScript editor, a PHP editor, and a PHP debugger. This all includes the standard features such as code completion, code collapsing, browser preview, project management, FTP, and so forth. The professional version includes all of those features, plus plug-ins for specific tools and frameworks: CakePHP, CodeIgniter, Drupal, jQuery, Joomla, Smarty, Symfony, WordPress, and Yii. In other words, the professional version gives you code completion, contextual help, and so forth for these additional tools that you may also be programming in.
As I said, I haven’t personally used it, but if you’re looking for a PHP/Web Development IDE, it may be worth checking out.
