How can error reporting be increased in PHP to easily identify and troubleshoot issues in code?

To increase error reporting in PHP and easily identify and troubleshoot issues in code, you can set the error reporting level in the PHP configuration file or in your script using the `error_reporting` function. By setting the error reporting level to `E_ALL`, you can ensure that all errors, warnings, and notices are displayed, making it easier to pinpoint issues in your code.

// Set error reporting level to display all errors, warnings, and notices
error_reporting(E_ALL);
