How to get response as json format(application/json) in yii?

Answer 1

In the controller action that you want to render JSON data, e.g: actionJson()

public function actionJson(){
    $this->layout=false;
    header('Content-type: application/json');
    echo CJSON::encode($data);
    Yii::app()->end(); // equal to die() or exit() function
}

See more Yii API

Answer 2

$this->layout=false;
header('Content-type: application/json');
echo CJavaScript::jsonEncode($arr);
Yii::app()->end();
