    In a HTML form that is processed by PHP:

    Hello

    World!
    Would that be output to the browser as:

    Hello

    World!
    or

    HelloWorld!
    In other words, do you have to do any sort of special formatting in PHP to make it recognize multiple line breaks?

    look at this sample:
    Code:
    $message .= "Hello: " . htmlspecialchars($_POST['hello'], ENT_QUOTES) . "<br>\n";
      $message .= "World: " . htmlspecialchars($_POST['world'], ENT_QUOTES) . "<br>\n";

    I'm sorry, but I don't really understand how that accomplishes what I'm trying to do. What I want to do is when someone types:

    This

    and this


    into a HTML form, for the output to be displayed as:

    This

    and this

    rather than

    Thisand this

    I apologize if I didn't make my first post clear enough

    Either output the text within <pre>...</pre> tags, or run it through the nl2br() function:
    PHP Code:
    echo "<pre>" htmlentities($text) . "</pre>\n";
    // . . . or . . .
    echo "<p>" nl2br(htmlentities($text)) . "</p>\n"

    Does either method have an advantage over the other?

    The nl2br is probably best. However, it outputs <br /> so if you are using HTML DOCTYPE, you probably better use
    Code:
    preg_replace("/\n/","<br>",htmlentities($text));

    Ultimately, it comes down to what you are trying to output and how semantically meaningful you want your resulting HTML mark-up to be. You might want to break it up into HTML <p>aragraphs, with:
    PHP Code:
    echo "<p>" preg_replace('/[\r\n]+/'"</p>\n<p>"htmlentities(trim($text))) . "</p>\n"
