how to create directories for the user uploads

i want that each user has its own directory in the main uploads directory and all its uploads are saved in there

how can i create a directories for the users in the yii

is there any way to do that?

You can use the php function mkdir() for that.

thanks it works fine

$folder=Yii::getPathOfAlias('webroot.documents.model').DIRECTORY_SEPARATOR;// folder for uploaded files

// you can use the ID or any property that is unique to the model
