HELP: ereg_replace()

[dahkiam]

I am trying to build a function that will parse some text containing some custom tags into proper html tags.

the tags are [b|u|i][/(b|u|i)], [link=url][/link],

.

function safeHTML($pText)
{
$text = htmlspecialchars($pText);
//replaces custom tags with standard ones
//$text = ereg_replace("[([b|i|u])]+" . "(????)" . "[\/([b|i|u])]", "<\1>\2</\1>", $text);

	//quote
	$text = ereg_replace("\[quote\]" . "(????)" . "\[\/quote\]", "<blockquote>\"<i><font color=#666666>\\1</font></i>\"</blockquote>", $text);

	//anchor tags: <a>*.*</a>
	$text = ereg_replace("\[link=+ *([^>]+)*\]" . "(???)" . "\[\/link\]", "<a href=\"\\1\" target=\"_blank\">\\2</a>", $text);

	//returns output
	return $text;
}

what do I need to put where in place the '????'?

For those who are intereted in the solution

ereg_replace is a bitch

function safeHTML($text)
{
$text = stripslashes($text);

		  	$text = htmlspecialchars($text);
		  	//$text = strip_tags($text, '<a><b><i><u>');

			//replaces custom tags with standard ones
			$text = preg_replace("/\[([b|i|u])\](.+?)\[\/([b|i|u])\]/si", "<\\1>\\2</\\1>", $text);

			//quote
			$text = preg_replace("/\[QUOTE\](.+?)\[\/QUOTE\]/si", "<blockquote>\"<i><font color=#CCCCCC>\\1</font></i>\"</blockquote>", $text);

			//anchor tags: <a>*.*</a>
			$text = preg_replace("/\[link=(.+?)\](.+?)\[\/link\]/si", "<a href=\"\\1\" target=\"_blank\">\\2</a>", $text);

		   	return $text; 
		}
