Tag Replacements in vBulletin...

[TheComputerGuy]

I'm trying to program a new tag replacement (such as quote or color) that would generate a random die throw (dice), and I'm doing it by modifying code from a phpBB hack. I'm asking how I can convert the following code to work with vBulletin:

$occurances = preg_match_all("#\[dice\]([-\s\w+/*]*?)\[/dice\]#i", $text, $temp); 
    
   //list($usec,$sec)=explode(" ",microtime()); 
   mt_srand((double)microtime()*1000000);//$sec * $usec); 
    
   // Loop to fix randomness problem of results when multiple die rolls are made in a single post - Hades 
   for($i=0;$i<=$occurances;$i++) 
   { 
      $dice_seed = mt_rand(); 
       
      $text = preg_replace("#\[dice\]([-\s\w+/*]*?)\[/dice\]#i", "[dice:$uid]\\1 = $dice_seed [/dice:$uid] $limit", $text, 1); 
      $text = preg_replace("#\[dice=(\\\\\".*?\\\\\")\]([-\s\w+/*]*?)\[/dice\]#i", "[dice:$uid=\\1]\\2 = $dice_seed [/dice:$uid] $limit", $text, 1); 
   } 
   $text = preg_replace("#\[dice\]([-\s\w+/*]*?)=([\s\d]*?)\[/dice\]#i", "[dice:$uid]\\1 = \\2 = Fixed[/dice:$uid]", $text); 
   $text = preg_replace("#\[dice\]([-\s\w+/*]*?)=([\s\d]*?)=\s*?Fixed\s*?\[/dice\]#i", "[dice:$uid]\\1 = \\2 = Fixed[/dice:$uid]", $text); 
   $text = preg_replace("#\[dice=(\\\\\".*?\\\\\")\]([-\s\w+/*]*?)=([\s\d]*?)\[/dice\]#i", "[dice:$uid=\\1]\\2 = \\3 = Fixed[/dice:$uid]", $text); 
   $text = preg_replace("#\[dice=(\\\\\".*?\\\\\")\]([-\s\w+/*]*?)=([\s\d]*?)=\s*?Fixed\s*?\[/dice\]#i", "[dice:$uid=\\1]\\2 = \\3 = Fixed[/dice:$uid]", $text);

I simply don't know enough about Regular Expressions to know how to change them around to work as one statement and fit it into the code that vBulletin uses:

	$bbcodes['custom']['find']['[dice]'] = 'What goes here?';
	$bbcodes['custom']['replace']['[dice]'] = "handle_bbcode_dice('\\2')";
	$bbcodes['custom']['recurse']['dice'][0] = array('handler' => 'handle_bbcode_dice');

P.S., I have a function called handle_bbode_dice, and a template.

Thank you to anyone that assists with this.
