What debugging techniques can be employed to troubleshoot PHP scripts effectively?

To troubleshoot PHP scripts effectively, you can employ techniques such as using error reporting, logging, and debugging tools like Xdebug. By enabling error reporting, you can easily identify syntax errors or runtime issues in your code. Logging can help track the flow of your script and identify where errors occur. Xdebug is a powerful debugging tool that allows you to step through your code, set breakpoints, and inspect variables to pinpoint issues. 

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

// Implement logging
ini_set('log_errors', 1);
ini_set('error_log', 'error.log');

// Use Xdebug for debugging
// Install Xdebug extension and configure your IDE for debugging
