Converting <enter> To \n In Textbox

I'm making a script that emails data and in the message box, I need all <enter> to be converted to \n so when it is mailed, it will format properly into:Thisis atestWhen submitted, it would be turned into:This \n is \n a \n testSo that it can easily be mailed. Or does PHP do this automatically? Thanks![N]F

Lets say your textarea box in a form where the message is entered is called message then in you form processing page if you are wanting to e-mail what was entered in the textarea so you would access the data in the textarea with $_POST['message'] and to use your message variable first make a short variable out of it like $message = $_POST['message']; then for the mail() function you would use wordwrap tomake sure that there are no more than 72 characters per line with the below code.

$message = wordwrap($message, 72, "<br>\n');

This will allow you to send the mail with no errors, by default mail will be sent in plain text but if you enter several returns or line breaks they will show up on plain text through the mail, or you would need to use <br /> tags (in the textarea), you would also have to format the message with the HTML tags you want to use if you set up your extra headers to send the mail with HTML.

Well, I don't know if you need it, but if you don't want to send html emails from your web server, you also would need to use strip_tags() function -> http://php.net/strip_tags - it will strip all html and php tags from the function, then you could use wordwrap. Or if the server has magic quotes on, you also would need to make stripslashes() so maybe you could use this code:

 

<?phpif (isset($_POST['message']) ) {	$message = wordwrap(strip_tags(stripslashes($_POST['message']) ), 72, "\n");	if (FALSE !== mail(/* Your Parameters */) ) {		echo 'Mail send with Success' . "\n";	} else {		echo 'Error: Could not send Mail' . "\n";	}}?>

Of course, sometimes you want the HTML code to be in the mail, so you can just remove the strip_tags() function.
