What are the potential issues with using tables for website layout in PHP development?

Using tables for website layout in PHP development can lead to accessibility issues, as tables are meant for displaying tabular data, not for layout purposes. It can also make the code harder to maintain and less responsive to different screen sizes. To solve this issue, it's recommended to use CSS for layout and positioning elements on the page.

<!DOCTYPE html>
<html>
<head>
    <style>
        /* CSS for layout */
        .container {
            display: flex;
            justify-content: center;
            align-items: center;
            height: 100vh;
        }
    </style>
</head>
<body>
    <div class="container">
        <!-- Content goes here -->
    </div>
</body>
</html>
