How can you limit the display of text to only the first 5 lines in a PHP newsletter system?

To limit the display of text to only the first 5 lines in a PHP newsletter system, you can use the `substr` function to extract the first 5 lines of text from the content and then use `nl2br` function to convert newlines to HTML line breaks for proper display. 

<?php
$text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.
Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.";

$lines = explode("\n", $text);
$first_5_lines = implode("\n", array_slice($lines, 0, 5));

echo nl2br($first_5_lines);
?>
