PHP Funktion: einmal geht, mehrmals nicht

[Kinman]

Hi, ich bin schon völlig am verzweifeln..
folgende Funktion funzt beim ersten mal einwandfrei aber sobald ich sie ein zweites mal aufrufe, funktioniert sie nicht mehr korrekt...
Sobald ich die IFs vor den schleifen aktivier (also eine while schleife aus der do while mache) funktionierts überalle, aber ineinandergeschachtelte bbcode funzen dann nimmer...

EDIT: Ups funzt nur dann nicht, wenn der BBCode ganz am Anfang steht...


<?php
function BBCode($message)
{
$message = trim($message); //Delete whitespaces in front and at the end of the message

$message = str_replace("\n", "<BR>", $message); //Convert breaks into <BR>
// $message = str_replace(" ", "&nbsp;&nbsp;", $message); //Convert whitespaces to &nbsp;


$message = str_replace("\\\"", "\"", $message); //Delete the \ in front of a "
$message = str_replace("\'", "'", $message); //Delete the \ in front of a '


$message = str_replace("", "<B>", $message); //Bold text
$message = str_replace("", "</B>", $message); //Bold text
$message = str_replace("", "<B>", $message); //Bold text

Ich will dir ja nicht die Freude an dem ganzen Code da nehmen, aber ich hab es mit preg_replace_callback() und RegExps gelöst. Mein Code ist dann auch nur einige wenige Zeilen lang. Solltest du dir auch mal angucken.

THX, wenn etwas einfacher geht nimm ichs gern an ;)
