Codelobster PHP Edition

I strongly recommend you to try Codelobster PHP Edition.
It's a free PHP IDE, which also can be used like editor for HTML, PHP, CSS, JavaScript
files with very useful option Portable.

Shortly about basic features:

- Highlighting, autocomplete and context help for all supported languages
- PHP Debugger
- Pair highlighting, selection and folding
- Navigation by holding CTRL key for all items
- Tooltips for all functions including PHPDoc
- Preview in all browsers
- FTP/SFTP support
- HTML/CSS code insector

HTML/CSS code insector it's a very cool features for this freeware.
it allows to get proper code and set of styles,belongings to any
selected element.

Also I want to mark the presence of plugins for most of popular Frameworks:
Drupal, Joomla, JQuery, Smarty, WordPress, Facebook, CakePHP, CodeIgniter
which have an opportunity for easy installing and working with them
