Checking for and creating directories

I am looking for some help in checking if there is a folder, and if the folder is not created it will create it and place the file they uploaded in it.

So for example, user "Don" logs in. He uploads a file to his folder and creates his folder unless it has already been created.

 

You can use is_dir(string $filename) http://au.php.net/is_dir to check for the directory
And use mkdir (string $pathname) to create one if needed. http://au.php.net/manual/en/function.mkdir.php

 

Could you write an example?

 

that's the jest of it.

 

//variable holds the username
$userName = $_POST['username'];

//checking if a directory does NOT exists with his name in the current directory
//create the directory
if(!is_dir($userName)))
{
  mkdir($userName)
}

//your upload code goes here

Code (markup):

Thats the basic idea
