What are some best practices for handling dynamically changing webpage lengths in PHP?

When handling dynamically changing webpage lengths in PHP, it is important to ensure that the content is displayed correctly regardless of the length. One way to achieve this is by using CSS to style the webpage layout in a responsive manner. Additionally, using PHP functions to dynamically generate content based on the length can help ensure that the webpage remains visually appealing.

<?php
// Example PHP code snippet to handle dynamically changing webpage lengths

// Retrieve content from a database or API
$content = getContent();

// Loop through the content and display it
foreach($content as $item) {
    echo "<div class='item'>" . $item['text'] . "</div>";
}

// CSS styling for responsive layout
echo "<style>
    .item {
        width: 100%;
        padding: 10px;
        margin-bottom: 10px;
        background-color: #f9f9f9;
        border: 1px solid #ddd;
    }
    
    @media (min-width: 768px) {
        .item {
            width: 50%;
        }
    }
</style>";
?>
