What role does the count() function play in determining the display of navigation elements in PHP scripts?

The count() function in PHP is used to determine the number of elements in an array. In the context of displaying navigation elements, the count() function can be used to check if there are enough items in an array to display navigation links. By using count() to count the number of items in an array and then checking if it meets a certain threshold, we can dynamically determine whether to display navigation elements based on the available data. 

// Sample array of navigation items
$navigationItems = ['Home', 'About', 'Services', 'Contact'];

// Check if there are enough items to display navigation links
if (count($navigationItems) >= 2) {
    // Display navigation links
    foreach ($navigationItems as $item) {
        echo '<a href="#">' . $item . '</a>';
    }
}
