PHP to Handle API Return instead of print

My API End point has return statement instead of print or echo : e.g.

return json_encode($data);
instead of
print json_encode($data);

I have a curl caller to consume my API. When I try to display the result, it shows null. However if I change API End point to :

print json_encode($data);

I can see the result.

Any idea how can I deal with return statement.

Why? If print (or echo) does what you want, why do you want to use return?

You don't. If you want output you need to use print or echo. The whole point of return is to not do that. return is for passing data between functions/variables.

Wait, wait... Are you talking about REST API endpoints? If so, then it should return it's value and not print it, I believe... Could you show more of your code?

Something like below: Inside routes.php: Router::connect('/api/fetch', array( 'Controller' => 'FetchController', Action' => 'fetch', 'Method' => 'GET' ), $_GET ); Inside Controller: public function fetch( $DATA ) { echo "100"; //works #return 100; //doesn't }
