PHP nl2br() basic function

Question

Can somebody please help me with this mail script.

I\'m simply trying to send an html email and part of the message is from a user textarea, which puts in \\r\\n.

Answer 1

An alternative is to use HEREDOC.

$message = <<<OUTPUT
 <div> some text 
   <div> some more text </div>
 </div>
OUTPUT;
$message = nl2br($message);

Answer 2

$message_var_1 = 'test1 \r\n test2 \r\n test3';

PHP parses \r and \n only within ", not within '. So nl2br won't apply here.

$message_var_1 = "test1 \r\n test2 \r\n test3";
$message = '<div>
     <div>'.nl2br($message_var_1).'</div>
</div>';

This ought to work.

Answer 3

This string contains embedded newlines so you'll end up with a few unwanted <br/>s.

$message = nl2br("
    <div>
    <div>$message_var_1</div>
    </div>
");

You can:

$message = "<div>" . nl2br($message_var_1) . "</div>";

Or, its much easier to use a <pre> tag:

$message = "<pre>$message_var_1</pre>";
