Davey Shafik has put together a list of four of the more popular PHP IDEs offered today - Zend Studio, Eclipse with the PDT extension, Komodo and NetBeans - and posted a comparison table of key features and preferences.
I have continued using Zend Studio 5.5 but have been looking for alternatives as it will not be updated to support new features like Namespaces, Closures and Traits. So far, I have tried Zend Studio for Eclipse/PDT, PHPEclipse (briefly), Komodo IDE and Netbeans. None of them have come close to replacing ZDE except for Netbeans. Below is some requirements and a comparison table for these I have tried so far.
He includes the specifications he's evaluating them on (including cross-platform with Windows, Linux and OS X) and the full list of "yes", "no" and "sort of" for each thing on the list. The criteria include:
- Inclusion of a debugger
- Inclusion of a profiler
- Auto-complete for user code and PHP functions
- Integration of revision control
- Project support
- Customizable interface
