How does error reporting and display settings impact the visibility of errors like "NULL" object instances in PHP?

Error reporting and display settings in PHP impact the visibility of errors like "NULL" object instances by determining whether errors are displayed to the user or logged for the developer to see. To ensure that "NULL" object instances are properly handled and not displayed to users, error reporting should be set to a level that logs errors without displaying them on the screen. 

// Set error reporting level to log errors without displaying them
error_reporting(E_ALL & ~E_NOTICE);

// Handle "NULL" object instances gracefully
if ($object !== null) {
    // Perform operations on the object
} else {
    // Handle the case where the object is NULL
}
