About PHP

PHP runs ~70% of websites you visit — WordPress, Wikipedia, Slack, Etsy. Modern PHP (8.4) has type declarations, enums, readonly properties, and is genuinely fast. Don't sleep on it.

Our sandbox runs PHP 8.4 with all common extensions. Composer-style package install is available in Pro+ sessions.

Up to 600s execution time (Mega tier)

Use PHP with stateful sessions

Open a session once, then call execute repeatedly — variables, files, and installed packages persist between runs. Perfect for code interpreters and REPL-style agents.

# 1. Create a session
curl -X POST https://api.sandboxapi.dev/v1/sessions \
  -H "X-RapidAPI-Key: $KEY" \
  -d '{"language":"php","idle_ttl":300}'
# → {"id":"sess_abc","language":"php",...}

# 2. Execute — first call
curl -X POST https://api.sandboxapi.dev/v1/sessions/sess_abc/execute \
  -H "X-RapidAPI-Key: $KEY" \
  -d '{"code":"<?php $x = 42; var_export($x);"}'

# 3. Execute again — state carries over
curl -X POST https://api.sandboxapi.dev/v1/sessions/sess_abc/execute \
  -H "X-RapidAPI-Key: $KEY" \
  -d '{"code":"// Note: PHP processes are short-lived — sessions persist files between calls"}'
