PhpStorm 10.0.1 (Mac)
PhpStorm - PHP IDE that evolves with you
The editor actually "gets" deeply understands the code and structure, supporting PHP 5.3, 5.4, 5.5 and 5.6 for modern and old projects. It provides the best code completion, refactoring, on-the-fly error prevention, and supports more languages mixtures.
Perform many routine tasks from the IDE thanks to the VCS (Git, SVN, etc) integration, local history, support for remote deployment, remote PHP interpreters, Behat, SQL and databases, online tools commands, Vagrant, Composer, built -in REST client and SSH console with remote tools.
