Yii框架：保存上传的文件

Question

I'm using Yii framework for developing website. Here, I have a problem in save image file which uploaded to server.

Here is the code which I used for uploading image.

<input type="file" onChange="uploadImage(this);">

function uploadImage(obj) {
    var request_url = server_url + "uploadImage";
    var formData = new FormData();
    formData.append("photo", obj.files[0]);

    $.ajax({
            url: request_url,
            type: 'POST',
            data: formData,
            processData: false,
            contentType:false
        });
}

And in server part, I can see the file has uploaded but can't get the file.

public function actionUploadImage() {

   if (ISSET($_FILES['photo'])) {
       var_dump('is set photo');
       $temp = CUploadedFile::getInstanceByName('photo');
       var_dump($temp);
   }
}

It returns "is set photo" and "array(0){}". Please help me.
