Paid PHP Editors
Adobe Dreamweaver: Adobe hasn't left a stone unturned in the field of web development. Dreamweaver (the editor from Adobe that is used for developing applications in PHP, HTML, Cold Fusion, etc) provides excellent support for PHP and offers all the features a good standard PHP editor needs. But the editor is costs a fortune. Many other editors are available that do the same job but at a lesser rate or for free!
Expression Web: Expression Web from Microsoft is a very clean editor and doesn't offer a cluttered environment like many other editors. However there is no support for content management systems in Expression Web. This is really a huge drawback because the popular content management systems like Wordpress, Drupal, Joomla, etc are designed using PHP and the support of a PHP editor to edit the content management systems to customize to one's need is important. Hence Expression Web as a PHP editor is good only for the starters who develop in PHP.
