I have a DMN table and a Symfony 2 project. They communicate by WS.
In Postman, the DMN works very well:

I apply this example camunda-dmn-cloud-examples/php/dish-decision.php at master · camunda/camunda-dmn-cloud-examples · GitHub in my project:

 /**
     * @param Request $request
     * @Rest\Get("/api/decisions")
     */
    public function getBusinessRule(Request $request){
            if($request->get("amountInput") !=''){
                $amount = $request->get("amountInput");
            }
            if($request->get("keyTableDecision") !=''){
                $key = $request->get("keyTableDecision");
            }
            $data = array('variable'=>array(
                    'amount' => array(
                        'type' => 'long',
                        'value' => intval($amount)
                    )
                )
            );
            $service_url = 'http://myserver/engine-rest/decision-definition/key/'.$key.'/evaluate';
            $curl = curl_init($service_url);
            curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($curl, CURLOPT_POST, true);
            curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
            $data_string = json_encode($data);
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data_string);
            $curl_response = curl_exec($curl);
            curl_close($curl);
            $decoded = json_decode($curl_response);
            echo "You should have " . $decoded->outputs->value;
        }

An error message displays:

Can you help me ?

This is the solution: I change $decoded->outputs->value to $decoded[0]->outputs->value
