BBCode help

[EchoFool]

Hey,

 

 

I am trying to make a BBCode which quotes a post. But if a user quotes a post where the post they are quoting... contains a quote already from a previous post (still with me?) then the CSS messes up and im not sure why.

 

 

In short if you quote a post which is already quoting a post then the problem arises.

 

 

My function is:

 

 

<?php

function bbcode ($string)
{
        // All the default bbcode arrays.
        $bbcode = array(
                //Text Apperence
                '#\[b\](.*?)\[/b\]#si' => '<b>\\1</b>',
                //Other
                '#\[url=http://(.*?)\](.*?)\[/url]#si' => '<a href="\\1" target="_blank">\\2</a>',
                '#\[quote\](.*?)\[/quote\]#si' => '<div class="quote_body">\\1<>',
                '#\[img\](.*?)\[/img\]#si' => '<img src="\\1">',
        );
        $output = preg_replace(array_keys($bbcode), array_values($bbcode), $string);
        return $output;
}


echo nl2br(bbcode($message));
?>

 

 

The HTML came out like this:

 

 

<div class="quote_body">
Posted By <b>Username</b> <br/>
[quote] Posted By <b>Username</b> <br/> 
Content of post
<br /><br/>
Content of post [/quote]
<br/><br/>
Content of Post

As you can see above some times it didn't change "quote" it left it and didn't convert it to my CSS. Any idea why?
