What is the issue the user is facing with truncating text in PHP?

The user is facing an issue where they need to truncate text in PHP to a specific length but preserve whole words. One way to solve this is by using the `substr` function along with `strrpos` to find the last occurrence of a space within the specified length and truncate the text at that position. 

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

// Example usage
$text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
$truncatedText = truncateText($text, 30);
echo $truncatedText; // Output: Lorem ipsum dolor sit amet...
