Question

I have a PHP file which creates a unique directory for each user when a file is uploaded. I would like the script to check and see if the directory already exists and if so then skip the mkdir action. Here is my code sample:

<?php
$thisdir = getcwd(); 
$new_dir = "123";
$full_dir = $thisdir . "/upload/" . $new_dir;

if(mkdir($full_dir, 0777))
{
echo "Directory has been created successfully... <br>";
}
else
{
echo "Failed to create directory...";
}
?> 

To continue this example, please assume that the folder “123” already exists. How do I modify it for this case? I am thinking it must be some sort of if…else statement. Thanks for going through this issue.

function maybe_mkdir($path, $mode) {
    if(is_dir($path)) {
        return TRUE;
    } else {
        return mkdir($path, $mode);
    }
}
