Daemons with PHP: Should you really do that? | Arne Blankerts

Explore the pros and cons of using daemons with PHP, including security concerns, complexity, and management options, and discover best practices for implementing and debugging daemons in your PHP applications.

Key takeaways
  • Daemons with PHP are not a best practice due to security concerns and added complexity.
  • Long-running processes can lead to memory leaks, CPU utilization issues, and errors.
  • Using systemd to manage daemons is a viable option.
  • Writing a PHP daemon process can be done, but requires additional configuration and error handling.
  • Forking processes via PCNTL can be beneficial, but requires careful consideration of resource usage.
  • Using FPM (FastCGI Process Manager) with PHP can help manage daemon processes.
  • Creating a PID file to monitor process status is a good practice.
  • Debugging long-running processes can be challenging due to lack of clear signals and logging.
  • Implementing connections using WebSockets requires careful consideration of service management.
  • Systemd timers can be used to trigger tasks and process events in a scheduled manner.
  • Using UDFs (user-defined functions) and custom protocols can be beneficial for specific use cases.
  • For simple cases, a single process can be used to handle requests and events.
