hello everyone and thanks in advance, I wanted to cosultar, the way to work with a web sevices in php to colsultar data in firebase, since when working with angular2 the data that I store is committed to leave the connection in enviroment, my intention is to avoid that. A thousand thanks and sorry if the question is very silly. I search the internet and I can not find anything concrete.
If your concern is the exposure of the Firebase connection data you can rest assured that in no way that enables an attacker to access your data as long as you have the BAD access rules configured.
If you are still interested in accessing Firebase from the server side on the SDK Admin (native library) to access Firebase from server) is available for Java, Node and python at this time. But you can still use the access via the REST API , in fact there are third-party libraries implemented in PHP here and here .
