PhpStorm PHP Interpreter Setup
Point PhpStorm at the correct local, WSL, Docker, or remote PHP executable for a Composer project.
Interpreter vs language level
PhpStorm separates the PHP executable used to run tools from the language level used for inspections. Set both from the project’s Composer constraints and deployment runtime, not from whichever PHP happens to be first on PATH.
Local, WSL, and container interpreters
For native installs, select the exact binary and validate with php -v inside PhpStorm’s terminal. For WSL or Docker, configure the matching interpreter type and keep source trees on the filesystem that interpreter expects so indexing and path mappings stay coherent.
Composer and quality tools
After the interpreter is correct, attach Composer, PHPUnit, PHPStan/Psalm, and coding-standard tools to that same runtime. A mismatch between CLI PHP and the web SAPI is a common source of “works in the IDE, fails in the browser.”
Acceptance checklist
Confirm php -v, php --ini, Composer platform PHP, one PHPUnit run, and one web request share the intended major.minor version. Document the approved path for the team.
Verification and maintenance
