A PHP client library for communicating with Socket.IO servers, enabling real-time event-driven interactions.
Elephant.io is a Socket.IO client library for PHP that enables PHP applications to communicate with Socket.IO servers. It solves the problem of integrating PHP with real-time, event-driven systems by providing a clean API to send and receive events over WebSocket or polling transports. This allows PHP backends to participate in real-time interactions typically handled by Node.js or other technologies.
PHP developers who need to integrate their applications with real-time features, such as chat systems, live notifications, or collaborative tools that use Socket.IO servers. It's also valuable for developers maintaining legacy PHP systems that require modern real-time capabilities.
Developers choose Elephant.io because it offers a pure PHP solution with extensive Socket.IO version support, eliminating the need for additional services or language bridges. Its comprehensive configuration options and detailed debugging capabilities make it a reliable and flexible choice for production real-time integrations.
Send events to a socket.io server through PHP
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports versions from 0.x to 4.x, ensuring seamless integration with diverse server implementations, as noted in the built-in engines list.
Automatically upgrades from polling to WebSocket for performance and allows explicit transport configuration via options like 'transport' and 'transports'.
Integrates with PSR-3 logging for detailed stream-level logs, demonstrated in the debugging example with verbose connection and packet data.
Offers fine-grained control over authentication, headers, binary data, and persistent connections, as detailed in the options section.
The wait() method for receiving events risks termination by PHP's max_execution_time, limiting its use for persistent real-time sessions without CLI workarounds.
Binary data defaults to PHP resources requiring manual fseek operations, adding overhead and potential for errors in data processing.
While functional, there's no built-in support for popular PHP frameworks like Laravel or Symfony, requiring custom integration efforts.
