What are some potential pitfalls to watch out for when migrating PHP code from a local environment to a live server?

One potential pitfall when migrating PHP code from a local environment to a live server is file path discrepancies. Make sure to update any hardcoded file paths in your code to match the directory structure of the live server.

// Before migration
include 'local/path/to/file.php';

// After migration
include 'live/server/path/to/file.php';
