What are some best practices for troubleshooting PHP scripts that suddenly stop functioning properly?

Issue: When a PHP script suddenly stops functioning properly, it could be due to syntax errors, missing dependencies, or server configuration issues. To troubleshoot, check for error messages in the PHP error log, review the code for any recent changes or mistakes, and ensure all necessary libraries and extensions are properly installed. 

// Example PHP code snippet to troubleshoot script issues
