how to create a sub-directory inside an existing parent directory

Question

In my site root I have a directory called uploaded and I have another directory called inc where i store my functions file.

When user registers I want to create a sub-directory inside the uploaded parent directory.

To my knowledge i have to step out of the inc directory using the ../ so i could get into the uploaded directory and successfully create the sub-directory inside using the mkdir()

I tried this but it does me no good:

<?php

$username = "jamesodurojbe";
$root = dirname(__FILE__);
    $dir1 = $root . "../uploaded/$username";
    if(!is_dir($dir1)){
     mkdir($dir1);
    }

?>

please help

Answer 1

Use the third parameter of mkdir():

$path = '/path/to/folder/with/subdirectory';
mkdir($path, 0777, true);

Answer 2

In my case I had to step out of the inc direction with the leading

/../uploaded/$username

The whole code had to look like:

//create user account directory folder for uploads
    $root = dirname(__FILE__);
    $dir1 = $root . "/../uploaded/$username";
    if(!is_dir($dir1)){
     mkdir($dir1);
