What factors should be checked when a PHP script runs successfully on a local server but encounters errors on a live website?

When a PHP script runs successfully on a local server but encounters errors on a live website, there are several factors to check. These include differences in server configurations, file paths, PHP versions, database connections, and error reporting settings. To solve this issue, ensure that the server configurations on the live website match those of the local server, update file paths to reflect the live environment, verify compatibility with the PHP version on the live server, check database connection details, and adjust error reporting settings to display errors on the live website.

// Example code snippet to adjust error reporting settings
error_reporting(E_ALL);
ini_set('display_errors', 1);
