How can the issue of a white screen be resolved when using the if(!isset($_GET["page"])) function?

Issue: The issue of a white screen when using the if(!isset($_GET["page"])) function can be resolved by checking if the $_GET["page"] variable is set before attempting to use it. This prevents PHP from throwing an "undefined index" notice and causing the white screen. Code snippet: 

if(isset($_GET["page"])) {
    $page = $_GET["page"];
    // Rest of your code here
} else {
    // Handle the case when $_GET["page"] is not set
    echo "Page not found";
}
