Attempting to match code style comments

[Prismatic]

Here's what I want to do, search through posted code and find the 3 most common types of comments,

 

/* */

//

and #

 

// and # are single line so I thought something like this would work

 

/** match //text */
$code = preg_replace("/\/\/(.*?)(.*?)/", " [color=green][b]//\\1[/b][/color] ", $code);

/** match #text */
$code = preg_replace("/\#(.*?)/", " [color=lightgreen][b]#\\1[/b][/color] ", $code);

 

However it's only grabbing the # and // leaving everything to the right out

 

And /* comments can run until they hit a */, which makes the multi line, I tried this but it also doesn't work

 

$code = preg_replace("/\/\*(.*?)\/\*/s", " [color=green][b]/*\\1*/[/b][/color] ", $code); 

 

anyone know what I need to do to make these work?

You might want to consider a pre-made syntax highlighter for PHP (many are available), the issue with any regex pattern for this operation would be how do you keep from matching your target strings within string declarations etc.
