php

I need change background of all text that have two spaces from the start of the line.

  text

shold be converted to "<div class='special'>text</div>"

That is easy:

$text = preg_replace("|^  (.+)|um", "<div class='special'>$1</div>", $text);

But

  line1
  line2

Is converted to

<div class='special'>line1</div>
<div class='special'>line2</div>

Though

<div class='special'>line1
line2</div>

is needed.

How that can be achieved?
