How to create a community portal using php frontend and java in the backend

As advised, define the feature set, performance goals and security needs before choosing an integration method. Since narrowed the immediate issue to "connecting frontend and backend," the most common, easiest-to-debug approach is to expose the Java side as HTTP APIs (REST/JSON) and have PHP act as a client. A Java REST framework (for example Spring Boot) makes endpoint creation and versioning straightforward, and PHP can call those endpoints using cURL or a library like Guzzle. See a Spring REST primer and the PHP cURL manual for concrete starting points: Spring REST guide PHP cURL manual.

Practical checklist: (1) design an API contract (URIs, HTTP methods, request/response JSON, error codes, versioning); (2) implement and test Java endpoints independently (use curl/Postman); (3) implement the PHP client with timeouts, retries and robust JSON parsing; (4) secure transport with HTTPS and token-based auth (JWT/OAuth2) and add logging on both sides. Familiarize with REST concepts if needed: REST (MDN).

Alternatives and quick troubleshooting: use a message broker (RabbitMQ, ActiveMQ) for async jobs or high-throughput decoupling (RabbitMQ get started). Avoid using a shared database as the primary IPC mechanism unless there is no other choice. When things fail, check HTTP status codes, Content-Type headers, authentication failures, and network/firewall rules; add short-lived POCs and detailed logs to isolate problems quickly.

help me creating a community portal??

I think that it's reasonable that you would define your needs more completely and that you would do some of the research instead of posting a totally open-ended question on a forum such as this.

You should provide more detail on what you want this "community portal" to be able to do. You also need to define your objective. Is this a PHP learning exercise or do you want to install a package and get it running as quickly as possible. The more detail you can provide (within reason), the more likely that someone will be able to provide some useful suggestions.

the more specific problem is connecting frontend and backend
