How can a PHP developer ensure that specific line breaks are preserved while using regex for text manipulation?

When using regex for text manipulation in PHP, the newline characters (\n) may be treated differently depending on the operating system. To ensure that specific line breaks are preserved, the PHP developer can use the "s" modifier in the regex pattern to make the dot (.) match all characters, including newlines. This allows for accurate manipulation of text while preserving line breaks. 

$text = "Hello\nWorld";
$pattern = '/Hello.*World/s';
$replacement = "Goodbye";
$new_text = preg_replace($pattern, $replacement, $text);
echo $new_text;
