phpscript - A custom PHP-flavoured runtime written in Go
This is a PHP interpreter written in Go. It supports the basic php expression syntax and some parts of the standard library. It's currently rudimentary and only enables limited functionality.
- About phpscript
- Language reference and PHP compatibility
- Installation and usage
- Configuration
- Testing and extending tests
- Naming conventions
- Go Reference
- Building an application
- Use cases
Current state
Several unit focused test fixtures exists, namely:
- interfacing Go code from the PHP VM for callbacks,
- database client and usage from PHP side (bring your own database/sql driver)
- loading and executing template engine code
This means that phpscript is currently able to use a generic Database client. Our own standard library implements a Database class which is integration tested with ./tests/fixtures/test-database.php over several databases (pgx, mysql, sqlite).
Building a docker image
You can build a docker image from source as follows:
CGO_ENABLED=0 go build -o bin/ .
docker build -t titpetric/phpscript:latest -f docker/Dockerfile .
See ./compose.yml for usage.

Package annotations discovers annotated PHP files in a source tree and gives them a lifecycle: routed endpoints are served over HTTP, startup jobs run once before the server listens, and scheduled jobs run on an interval.

compat
Package compat implements PHP language surface that a script expects to be there rather than a library it calls: functions whose behaviour is defined by what the interpreter does, not by what they compute.

span
Package span exposes telemetry spans to PHP as the start_span() binding, so a script can measure a region of its own work next to the spans the interpreter records for it.
