How can using IDs instead of descriptive names in file paths improve the robustness of PHP applications?

Using IDs instead of descriptive names in file paths can improve the robustness of PHP applications by reducing the likelihood of naming conflicts and making the code more scalable. IDs are unique identifiers that can easily be associated with specific resources, making it easier to locate and retrieve them programmatically. This approach also helps to prevent errors caused by human error in naming conventions.

// Using IDs in file paths
$id = 123; // Unique identifier for the resource
$file_path = "/path/to/files/{$id}.txt"; // Using ID in the file path
$file_content = file_get_contents($file_path); // Retrieve file content using the ID
