Are there alternative methods to creating directories in PHP that are more secure and efficient?

When creating directories in PHP using functions like `mkdir()`, it is important to ensure that the directory is created securely and efficiently. One alternative method to create directories in a more secure way is by using `mkdir()` function with the appropriate permissions set explicitly. This helps prevent unauthorized access and ensures that the directory is created with the correct permissions.

// Create a directory with specific permissions
$dir = 'path/to/new/directory';
$permissions = 0755; // Set the appropriate permissions for the directory

if (!file_exists($dir)) {
    mkdir($dir, $permissions, true);
}
