Are there best practices for ensuring that complete sentences are displayed when truncating text in a news script using PHP?

When truncating text in a news script using PHP, it is important to ensure that complete sentences are displayed to maintain readability and coherence. One way to achieve this is by finding the last occurrence of a sentence-ending punctuation (such as a period, question mark, or exclamation point) within the truncated text and displaying everything up to that point. Here is an example PHP code snippet that demonstrates this approach: 

```php
function truncateText($text, $maxLength) {
    if (strlen($text) <= $maxLength) {
        return $text;
    }
    
    $truncatedText = substr($text, 0, $maxLength);
    $lastSentenceEnd = strrpos($truncatedText, '.');
    if ($lastSentenceEnd !== false) {
        $truncatedText = substr($truncatedText, 0, $lastSentenceEnd + 1);
    }
    
    return $truncatedText;
}

// Example usage
$text = "This is a sample sentence. It should be truncated at the end of this sentence.";
$maxLength = 30;
$truncatedText = truncateText($text, $maxLength);
echo $truncatedText;
```

In this code snippet, the `truncateText` function takes the original text and a maximum length as input. It checks if the text is already shorter than the maximum length and returns it as is if true. Otherwise, it truncates the text to the specified length and finds the last occurrence of a sentence-ending punctuation. The truncated text is then adjusted to end at the last sentence-ending punctuation, ensuring that complete sentences are displayed.
