I need to connect PHP client code to JAVA backend, where the actions are :
1. http request will be sent from PHP client.
2. It will interact with JAVA code on Model and will store data in Nosql using JAVA backend
I read about this php-java bridge
Which can be better PHP-JAVA bridge to use?
Take a look at Project Zero and Quercus. Both of those may be helpful. The php-java bridge that you linked to may prove most useful though as its built to work with the official PHP distribution.
