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);
答
Your $jsonfile variable contains the file URL, while it should contain your file's path in the server. Check the predefined aliases.
For example:
$jsonfile=Yii::getAlias('@app').'/assets/json/aresult.json';
