Yo.... where's the love for the JetBrains IDEs?
PHPStorm and its big brother, IntelliJ Idea are my two new favorite IDEs for PHP.
They're both significantly faster than Eclipse and NetBeans for project-wide-search and open-file-by-name, because of how they index your project.
I've been using IntelliJ Idea for about a month now... it's basically PHPStorm + PyCharm + awesome Java editing + pretty much anything else you need... so if you're a multi-faceted programmer, it's probably ideal for you.
Only downside is it costs money. $199 for an individual license.
I guess you get what you pay for!
