Are there specific changes in notice handling between PHP 5.3 and PHP 7.3 that could affect webpage display on an IIS server?

In PHP 7.3, the way notices are handled has changed compared to PHP 5.3. This change could potentially affect webpage display on an IIS server if the code relies on specific notice handling behavior. To address this issue, you can modify the error_reporting directive in your PHP configuration to adjust how notices are displayed or logged.

// Adjust error reporting to handle notices differently
error_reporting(E_ALL & ~E_NOTICE);
