VS Code Composer for PHP
Run Composer from VS Code without hiding platform requirements from the team.
Terminal first
Open the integrated terminal in the Composer root and use the project’s documented PHP binary. Confirm composer --version and php -v before installing packages.
Tasks and problem matchers
Add tasks for install, update (when allowed), validate, and dump-autoload. Prefer composer validate and composer check-platform-reqs during onboarding.
Platform config traps
config.platform.php in composer.json can make installs succeed while the runtime differs. Surface platform checks in CI and in the IDE terminal so “green install” is not a false comfort.
Remote and containers
When using Remote SSH or Dev Containers, run Composer inside the remote environment so vendor/ matches Linux production, not a mismatched local Windows PHP.
Verification and maintenance
VS Code Composer for PHP was reviewed for this seed on 2026-08-09. Confirm current releases and extension publishers through Composer Documentation before adopting recommendations.
