I have been using phpDesigner for a long time, and have been fairly happy with it.
However, the code explore and completion feature is a bit sub-par and doesn't pick up on a lot of classes.
I have been looking for a suitable replacement.
So far I've looked at Eclipse and NetBeans but they both seem to have their shortcomings. For example, I could never get syntax highlighting to work right in Eclipse when PHP is mixed with HTML content, as in templates. Netbeans has better support for remote projects and mixed PHP/HTML, but the autocompletion is a bit off sometimes. The auto formatting also gives me headaches.
What do you guys use?
I am not interested in a lightweight editor, I need full code completion and possibility to debug the code. Windows+Linux preferred, but Windows-only programs are okay.
