when you say "lines" you mean linebreaks? as in carriage returns? if so consider this example:

$text = 'this is line 1
this is line 2
this is line 3
this is line 4
this is line 5
this is line 6
this is line 7
this is line 8
this is line 9
this is line 10';

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

echo 'first 5 lines:<br>' . nl2br($first_5_lines);
echo '<br><br>';
echo 'rest:<br>' . nl2br($rest);

if you mean lines as in wherever the wordwraping occurs then you will have to break it up by number of words/characters.
