PhpStorm 2026.3 adds Air, PHP 8.6 and remote tools

PhpStorm 2026.3 introduces JetBrains Air, an in-IDE workspace for running supported coding agents, managing multi-agent setups, and reviewing changes alongside project files and diffs.

The update adds PHP 8.6 compatibility checks, code insight, inspections, and quick-fixes, plus expanded type inference and Laravel inspections.

It also improves WSL and remote development with automatic PHP detection, Xdebug forwarding, integrated SSH sessions, light mode, and native OpenSSH support.
