Some essential plugins for Jetbrains IDE PHP Storm
The deep assoc completion plugin allows you to autocomplete associative arrays
Very good plugin for the Symfony framework. Tons of autocompletion features of services, templates making the developer experience of Symfony ultimate.
Also offers twig support which is usable in other frameworks, such as Craft CMS.
The Jetbrains integrated terminal is nice but once in a while we'd like to open the native terminal with our customised color schemes.
