Can PHP Establish WebSockets Without External Libraries?

Is Native PHP Support for WebSockets Available?

Inquiring minds want to establish WebSockets with PHP, a language that typically operates within the realms of Apache, Nginx, or IIS. These environments often pose challenges for WebSocket implementations due to their lack of innate support for persistent connections.

The Lack of Native PHP WebSocket Support

To address this shortfall, PHP programmers must turn to external libraries to establish WebSocket functionality. These libraries function independently, operating as separate processes due to the limitations of Apache and IIS with regard to persistent connections.

Available PHP WebSocket Libraries

An array of options exists:

  • Apache Module: https://github.com/disconnect/apache-websocket
  • Ratchet: https://github.com/cboden/Ratchet
  • Wrench: https://github.com/varspool/Wrench
  • PHP WebSocket: http://code.google.com/p/phpwebsocket/

Additional Considerations

Remember that IE10 is now an integral component of Windows 8. Additionally, an Ajax push system may offer alternative solutions to consider.
