How can the error_reporting function be used correctly in PHP to help identify and troubleshoot errors?

The error_reporting function in PHP can be used to set the level of error reporting for the script. By setting the error_reporting level to E_ALL, all errors, warnings, and notices will be displayed, helping to identify and troubleshoot issues in the code. This can be especially useful during development and testing stages.

// Set error reporting level to display all errors
error_reporting(E_ALL);
