在现有文件Yii2框架中写入数据

Question

I am trying to write data in a json file from yii2 framework. It's returning error failed to open stream. My code is given below.

$productjson = json_encode($value);
echo $jsonfile=Yii::$app->view->theme->baseUrl.'/assets/json/aresult.json';
$fp = fopen($jsonfile, 'w+');
fwrite($fp, $productjson);
fclose($fp);

Answer 1

That's the right way to specify the path

 $productjson = json_encode($value);
 echo $jsonfile= Yii::getAlias('@webroot/assets/aresult.json');
 $fp = fopen($jsonfile, 'w+');
 fwrite($fp, $productjson);
 fclose($fp);

And yii2 has a class to work with json
