What are some best practices for using mkdir in PHP to avoid automatic folder deletion?

When using the mkdir function in PHP to create directories, it's important to set the correct permissions to prevent automatic folder deletion. To avoid this issue, you can explicitly set the permissions using the chmod function after creating the directory. This ensures that the folder is not accidentally deleted due to incorrect permissions. 

$dir = 'path/to/directory';

if (!file_exists($dir)) {
    mkdir($dir, 0777, true); // Create directory with full permissions
    chmod($dir, 0777); // Set correct permissions to prevent deletion
}
