如何保存所有JSON记录而不是最后一条记录

Question

这是我的代码，我正在尝试将所有记录保存在JSON文件中，但我最终只得到了最后一条记录。谢谢！

public class Moduletest extends ActivityInstrumentationTestCase2<Your Activity>{

 protected void setUp(){
    super.setUp();

    ActivityLifecycleMonitorRegistry.getInstance().addLifecycleCallback(new ActivityLifecycleCallback() {
      @Override public void onActivityLifecycleChanged(Activity activity, Stage stage) {
        if (stage == Stage.PRE_ON_CREATE) {
          activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        }
      }
    });
  }
}

这解决了我的问题

try {
    $output = $web_service->query($input);
    if($output['HTTP_OK'] == true) {
        print_r($output['DATA']);
        foreach (json_decode($output['DATA']) as $obj) {
            print_r($obj);
        }

    }

file_put_contents("data.json", $output['DATA']);
