Yii2: saveAs() doesn't work at other page

[KaungZawHtet]

I want to save a same file double time at 2 pages according to my requirement. First I try with session but nothing happened. And now I prefer to work with cache but still nothing happen.

actionOne()
{
$uploadObj= UploadedFile::getInstance($model, 'file');
$FileName = $uploadObj->name;
$url = 'uploads/' . $FileName ;
$uploadObj->saveAs($url,false); //it's work

$cache = Yii::$app->cache;
$cache->add('TestKey',$uploadObj,5);
// other codes below to go to 'two'
}

actionTwo()
{
$cache = Yii::$app->cache;
$uploadObj=$cache->get('TestKey');
$uploadObj->saveAs('uploads/new.file'); // this not work and no err

}

This is a PHP feature. Please visit PHP doc: POST method uploads

The file will be deleted from the temporary directory at the end of the request if it has not been moved away or renamed.

already read it. I don't know what I have to do with it. It's about getting info of uploaded file. I have checked the info of uploaded file with var_dump($uploadedobj).
I still need more exact way.

@KaungZawHtet The file $uploadObj->tempName deleted after actionOne() return. So, you don't save the deleted file in actionTwo(). This is a PHP feature.

Because actionOne() and actionTwo() are different requests.

Is there any good way that keep the uploaded file at storage within a time and delete it after that amount of time? Like cache concept that keep at storage instead of on RAM.

Suppose,
$cache = Yii::$app->cache;
$cache->add('TestKey',$uploadObj,5);
This code keep the cache on RAM for 5 seconds.After that, there will be automatically deleting. I want the way that work with storage instead of RAM.

You can call this "Automatic file deletion after a period". How can I get this?
If I know that way, I think I can relinquish the previous way.

@KaungZawHtet $cache store the $uploadObj object data, not store $uploadObj->tempName file (such as /tmp/Haj2Jsbw on linux) data.

You can get a "/tmp/Haj2Jsbw" string from the cached $uploadObj object data. But, the file /tmp/Haj2Jsbw is deleted on new request.

I will inform you back after reading some sources and making researches over this. For now, thx for your reply.

@KaungZawHtet

public function actionOne()
{
    $uploadObj = UploadedFile::getInstance($model, 'file');
    $FileName = $uploadObj->tempName;
    $data = file_get_content($FileName);
    $cache = Yii::$app->cache;
    $cache->add('TestKey', $data, 5);
}

public function actionTwo()
{
    $cache = Yii::$app->cache;
    $data = $cache->get('TestKey');
    file_put_content('uploads/new.file', $data);
}

@KaungZawHtet You could save base64 file data to session.
