Yii20 File Upload

1. Loading in the Controller interface

Use Yii\web\uploadedfile;

2. Receive the image and save it locally

  $file = uploadedfile::getinstancebyname (' photo ');            Save path            $path = ' images/';            Determine if the file exists            if (!file_exists ($path)) {                mkdir ($path);            }            Rename the file name            $file _name = Date (' y-m-d '). Mt_rand (0000,9999). $file;            $new _path= $path. $file _name;            $file->saveas ($new _path,true);
