How can PHP code be refactored to ensure the correct number of elements are displayed on a page without affecting the layout or functionality?

When refactoring PHP code to ensure the correct number of elements are displayed on a page without affecting the layout or functionality, you can use a loop to iterate through the elements and only display the desired number. You can achieve this by setting a counter variable and incrementing it within the loop. Once the counter reaches the desired number of elements, you can break out of the loop to prevent any additional elements from being displayed. 

<?php
$elements = ['Element 1', 'Element 2', 'Element 3', 'Element 4', 'Element 5'];
$desired_elements = 3;
$counter = 0;

foreach ($elements as $element) {
    echo $element . "<br>";
    $counter++;
    
    if ($counter == $desired_elements) {
        break;
    }
}
?>
