PHP - Bbcode: Preg_replace Error

Hi I'm trying to get rid of the deprecated functions like the eregi replace, but is currently experiancing a few problems.   I have the following function

function filterBadWords($str)
{
	
	
    $result1 = mysql_query("SELECT word FROM StringyChat_WordBan") or die(mysql_error()); 
    $replacements = "#~";
    
    while($row = mysql_fetch_assoc($result1))
    {
          $str = eregi_replace($row['word'], str_repeat('#~', strlen($row['word'])), $str);
    }  
    
    return $str;
}

and tried changing it into

function filterBadWords($str)
{
	
	
    $result1 = mysql_query("SELECT word FROM StringyChat_WordBan") or die(mysql_error()); 
    $replacements = "(G)";
    
    while($row = mysql_fetch_assoc($result1))
    {
          $str = preg_replace($row['word'], str_repeat('(G)', strlen($row['word'])), $str);
    }  
    
    return $str;
}

but now I'm getting errors like   preg_replace(): Delimiter must not be alphanumeric or backslash  Any help regarding this?

i get the following error in the comments in wordpress blog..:

I'm trying to work on BBCode for a forum. I have this:
Code: [Select]
<?php
$bb_Code = array(
'[ code]' => '<code>',
'[ /code]' => '</code>'
);
foreach ($bb_Code as $value => $replace) {
$text = str_replace($value, $replace, $text);
} ?>

Question is.. how would I get it so when I insert information into the database it gets cleaned (strip_tags, etc.) but doesn't disturb what is in the [ code ] tags?
So basically it makes the html, etc. in the [ code ] tags just plain text?

Thanks in advanced.
