I'm making a forum and I'm currently coding signatures. Is there a function that I can use to make sure that what the user inputs is a certain number of lines?

CODE
$lines = explode("/n", $string);

$number_lines = count($lines);

if ($number_lines < $req_lines) {
   // do whatever you want
}

I think you're looking for '\n'. And if the data is processed on a Windows-based server (although they usually run ASP and not PHP), '\r\n' is more likely to be the value of a new line. You could use operating-system detection features if you like, and 'explode' the string accordingly; it would make your code slightly more portable.

The explode worked, but \n didn't. I made it do nl2br and then explode the <br />'s. Thanks for the idea, though.
