function createNestedDirectory($path) {
    if (is_dir($path)) {
        return true;
    }
    $parent_dir = dirname($path);
    if (createNestedDirectory($parent_dir)) {
        return mkdir($path);
    }
    return false;
}

$path = "parent_directory/child_directory/nested_directory";
if (createNestedDirectory($path)) {
    echo "Nested directory created successfully.";
} else {
    echo "Failed to create nested directory.";
}
