PHP string wraping

[fileserverdirect]

Hello,
I have a script that emails me a form responce, But when the string was submitted, One long un-wraped line came up because the user never pressed enter, it just looked wraped. How (in php) can you add a new line after (lets say) 30 charaters and without disrupting a word so this doesn't happen:


Hello Joe,

use the wordwrap() function

e.g.

$text = "users input";

$message = wordwrap($text, 30);
