Use VS Code Remote SSH for PHP

Understand the execution boundary

Remote SSH connects the local VS Code interface to a remote host where workspace extensions, terminals, and project tools can run. Install the PHP language and debug extensions in the remote context when prompted, and keep PHP plus Composer available on that host.

Secure the host

Use least-privilege SSH keys, host verification, and a development account without production authority. Review forwarded ports and avoid placing secrets in workspace settings. A remote editor connection should not become a back door around deployment controls.

Configure Xdebug direction

The web runtime may be on the same remote machine or another container. Determine where Xdebug connects, use forwarding if required, and map paths as seen by PHP. Test one simple script before a framework request.

Make reconnection predictable

Verify terminal environment, extension installation location, Composer credentials, Git signing or authentication, and behavior after network loss. Store project commands in the repository so another approved client can reproduce the workflow.

Verification and maintenance

Use VS Code Remote SSH for PHP was reviewed for this seed on 2026-08-09. Before adopting its recommendations, confirm current releases, platform support, licensing, extension publishers, and configuration syntax through Visual Studio Code Remote SSH at the official source linked below. Product status and plugin compatibility can change independently of this editorial record.

Test changes on a representative repository and keep Composer scripts, automated tests, static analysis, and version control authoritative. If official documentation no longer supports a claim made on /ide/vscode/remote-ssh/, mark the fact unknown or update it from a primary source rather than filling the gap from an old tutorial or download mirror.
