No paragraphs and line break

Hi friends if there is no new lines formated you can use for your variable PHP Autoformat Paragraph tags.

See here: http://stackoverflow.com/questions/5240729/php-autoformat-paragraph-tags

$text = "hello, I am text

and this is another paragraph, please do some cool
stuff with this (this is after a  line break)

last apragrahp...";

$text = str_replace("\r\n","\n",$text);

$paragraphs = preg_split("/[\n]{2,}/",$text);
foreach ($paragraphs as $key => $p) {
    $paragraphs[$key] = "<p>".str_replace("\n","<br />",$paragraphs[$key])."</p>";
}

$text = implode("", $paragraphs);

echo $text;
