Rogue Wave Software's Zend Studio
The quick pitch for Rogue Wave Software's Zend Studio, recently updated to version 13.6, is "the PHP IDE for smarter development". Zend Studio 13.6, says Rogue Wave, offers 3X faster performance in indexing, validation and searching of PHP code, and it allows users to code faster, debug more easily and leverage the massive performance gains in PHP 7. It is the next-generation PHP IDE designed to create high-quality PHP apps while boosting developer productivity. The platform automatically scales according to the DPI settings of the underlying operating system and supports HiDPI monitors.
Finally, the release comes with the latest and greatest release of the Eclipse Platform, Neon.3, which brings with it its own slew of improvements.
