BBCode auswertung

    Ich habe ein BBCode system erstellt, es funktioniert auch, fast.
    Das Problem: Die BBCodes werden falsch ersetzt:

    Code
    //hier die BBCodes einfügen
$ersetzen = array("[b]","[/b]","[i]", "[/i]", "[u]", "[/u]", "[cid]", "[cid-label]", "[/cid-label]", "[/cid]", "[google]", "[google-label]", "[/google-label]", "[/google]" );
$ersatz = array("[b]","[/b]","[i]", "[/i]", "<u>", "</u>", "[url='index.php?id=', '']", "", "[/url]", "[url='http://www.google.de/search?hl=de&q=', '']", "", "[/url]", );
if(count($ersetzen)==count($ersatz)){
$count = count($ersatz);
for($i = 0 ; $i < count($count) ; $i++)
$contenttext = eregi_replace($ersetzen[$i],$ersatz[$i],$contenttext);


    Hier mal der Link zur Seite:

    nimm das hier:

    Code
    $ersetzen = array("[b]","[/b]","[i]", "[/i]", "[u]", "[/u]", "[cid]", "[cid-label]", "[/cid-label]", "[/cid]", "[google]", "[google-label]", "[/google-label]", "[/google]" ); 
$ersatz = array("[b]","[/b]","[i]", "[/i]", "<u>", "</u>", "[url='index.php?id=', '']", "[/url]", "[url='http://www.google.de/search?hl=de&q=', '']", "[/url]");
$contenttext = str_replace($ersetzen,$ersatz,$contenttext);

    Something big is coming. And there will be pirates and ninjas and unicorns...
