Buddy read this in detail, it will solve your problem, you need to parse signed_request, in signed_request you get the user_id, you can get signed request like this authResponse.signed_request

Alternatively you can use below Facebook graph api method in place of this line "$user_id= $facebook->getUser();" in your code.

FB.login(function(loginResponse) {
    if (loginResponse.authResponse) {
        var userId = loginResponse.authResponse.userID;

        // Work with userId here
        var signed_request = loginResponse.authResponse.signedRequest;
        //Work with signed request here
    }
    else {
        //User cancelled login or did not fully authorize        
    }
});
