What are common issues when creating directories with mkdir in PHP?

One common issue when creating directories with mkdir in PHP is permission errors, where the script does not have the necessary permissions to create the directory. To solve this, you can set the correct permissions on the parent directory or use the optional mode parameter in mkdir to specify the permissions. 

// Example code to create a directory with specific permissions
$dir = 'path/to/new/directory';
$mode = 0777; // Set the permissions here
if (!file_exists($dir)) {
    mkdir($dir, $mode, true);
}
