How does "safe mode" in PHP impact file and folder operations like creating directories?

When PHP is running in safe mode, certain file and folder operations, such as creating directories, are restricted for security reasons. To work around this limitation, you can use the `mkdir()` function with appropriate permissions set explicitly. 

$dir = 'new_directory';

// Check if the directory doesn't already exist
if (!is_dir($dir)) {
    // Create the directory with 755 permissions
    mkdir($dir, 0755);
}
