How can one effectively troubleshoot PHP errors in a script?

To effectively troubleshoot PHP errors in a script, you can start by enabling error reporting in your PHP configuration or at the beginning of your script using `error_reporting(E_ALL); ini_set('display_errors', 1);`. This will display any errors or warnings that occur during script execution. Additionally, you can use functions like `error_log()` or `var_dump()` to help identify the cause of the error.

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);
