PHP

Summary

Item	Value
API name	php
source OCI image	php:8.3-cli-alpine
per-job resource ceiling	1 vCPU, 512 MiB

The vCPU and RAM ceiling exists to prevent abuse; libkrun memory is elastic and the host only pays for what the guest touches.

Warmup

None: the official image already ships everything needed.

How the code is executed

The main file (the first in files) is executed with php <file> (CLI). The other files sit in the same directory and can be included with require. Everything runs in a directory under /tmp (tmpfs), in a fresh VM destroyed at the end of the job, with no network.

Building the image

rc image build --stack php

Example

curl -s http://127.0.0.1:8080/api/v1/run \
  -H 'Content-Type: application/json' \
  -d '{
    "language": "php",
    "files": [
      {"name": "main.php", "content": "<?php\necho strtoupper(trim(fgets(STDIN))), PHP_EOL;\n"}
    ],
    "stdin": "abc"
  }'

Expected stdout: ABC.
