How can PHP developers ensure that truncated text is displayed correctly with ellipses (...) at the end?

When truncating text in PHP, developers can ensure that it is displayed correctly with ellipses (...) at the end by checking the length of the text and appending the ellipses only if the text exceeds a certain character limit. This can be achieved by using the strlen() function to determine the length of the text and substr() function to truncate the text accordingly. 

function truncateText($text, $limit) {
    if (strlen($text) > $limit) {
        $text = substr($text, 0, $limit - 3) . '...';
    }
    return $text;
}

// Example usage
$text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
$truncatedText = truncateText($text, 20);
echo $truncatedText; // Output: Lorem ipsum dolor...
