How can PHP error reporting be used to troubleshoot issues with code execution and file handling in PHP scripts?

To troubleshoot issues with code execution and file handling in PHP scripts, you can enable error reporting to display any errors or warnings that occur during script execution. This can help identify the root cause of the issue and provide valuable information for debugging. By setting the error_reporting directive in your PHP script or configuration file, you can control the level of error reporting displayed.

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

// Your PHP code here
// This will display all errors and warnings during script execution
