How can adjusting the error_reporting level impact the functionality of PHP scripts?

Adjusting the error_reporting level in PHP can impact the functionality of PHP scripts by controlling which types of errors and warnings are displayed. Setting a higher error_reporting level will display more errors and warnings, which can help in debugging and identifying issues in the code. On the other hand, setting a lower error_reporting level may hide certain errors and warnings, potentially causing issues to go unnoticed.

// Set the error_reporting level to display all errors and warnings
error_reporting(E_ALL);
