How can PHP developers ensure that usernames are displayed appropriately in lists or menus without compromising the overall design?

When displaying usernames in lists or menus, PHP developers can ensure they are displayed appropriately by limiting the length of the username and using ellipsis (...) to indicate truncation if necessary. This helps maintain the overall design by preventing long usernames from disrupting the layout.

<?php
function displayUsername($username, $maxLength) {
    if (strlen($username) > $maxLength) {
        $username = substr($username, 0, $maxLength - 3) . '...';
    }
    echo $username;
}

// Example usage
$username = "verylongusername123";
displayUsername($username, 10);
?>
