[PHP] pobierz, plaintext 
$txt = nl2br($txt);
$txt = str_replace('\\n', "<br />", $txt);
$txt = preg_replace('/((.?)+)\n/', '$1<br /></p>', $txt);
[PHP] pobierz, plaintext 

i żaden sposób nie działa. Z góry dziękuje
Oto kod funkcji

[PHP] pobierz, plaintext 
function textShow($txt)
{
	$txt = preg_replace('/\[tex\]((.?)+)\[\/tex\]/', '<br />'.texTransform('$1').'<br />', $txt);
	$txt = preg_replace('/\[b\]((.?)+)\[\/b\]/', '<b>$1</b>', $txt);
	$txt = preg_replace('/\[i\]((.?)+)\[\/i\]/', '<i>$1</i>', $txt);
	$txt = preg_replace('/\[u\]((.?)+)\[\/u\]/', '<u>$1</u>', $txt);
	$txt = preg_replace('/\[p\]((.?)+)\[\/p\]/', '<p>$1</p>', $txt);
