• If the DATABASE_URL starts with postgres:// (Heroku's default), it replaces it with the correct format, postgresql+psycopg2://, making the URI compatible with SQLAlchemy.

Instead of manually replacing the URI, you can use libraries like dj-database-url to parse and adapt the DATABASE_URL for different frameworks or drivers. However, the manual approach is straightforward and works well for most cases.

To enable all error debugging in PHP, you can use the following PHP code snippet. This will display all errors, warnings, and notices:

<?php
// Turn on all error reporting
error_reporting(E_ALL);

// Display errors
ini_set('display_errors', 1);

// Optionally, you can log errors instead of displaying them
// ini_set('log_errors', 1);
// ini_set('error_log', '/path/to/php-error.log');

echo "Error reporting is enabled.";
?>
