undo html

[vividona]

I am using htmlspecialchars() function to change some of html tags

Now I need to highlight my php codes.

[code=php:0]public function bb_php($string)
{
	string = str_replace ( '&', '&', $string );
        $string = str_replace ( ''', '', $string );
        $string = str_replace ( '"', '', $string );
        $string = str_replace ( '<', '<', $string );
        $string = str_replace ( '>', '>', $string );

	$match = array('#\[php\](.*?)\[\/php\]#se');
	$replace = array("'<div>'.highlight_string(stripslashes('$1'), true).'</div>'");

	return preg_replace($match, $replace, $string);
}

 

This code undo html tags from the whole page.

I need to remove it only from php codes[/code]
