What role does the "pid" parameter play in determining whether a menu item is a main menu point or a submenu point in PHP scripts?

The "pid" parameter in PHP scripts typically stands for "parent ID" and is used to determine whether a menu item is a main menu point or a submenu point. By checking the value of the "pid" parameter, we can identify if the menu item should be displayed as a main menu point (if pid is NULL or 0) or as a submenu point (if pid corresponds to the ID of a main menu item). 

// Check if the menu item is a main menu point or a submenu point based on the "pid" parameter
if ($pid == NULL || $pid == 0) {
    // Display the menu item as a main menu point
    echo '<li>Main Menu Item</li>';
} else {
    // Display the menu item as a submenu point
    echo '<li>Submenu Item</li>';
}
