If this is for a templateting type of system for your site I would suggest to go a different route.

First your above code would change so that the portion between you code would look like:

[code]{{msg}}}[/code]

Now, you can still store your stuff in the database as php code if you want, but it makes more sense to eval it before you put it into the database, but I strongly suggest otherwise and go with a find/replace system.

Now, you would want to have a function that would do the following:

function output_template( $name, $data ) {
    $template_string = get_template_from_db( $name );
    for( $data as $k )
    {
        $template_string = str_replace( $k, $data[$k], $template_string );
    }
    return $template_string;
}

Then you can echo out the return value of this function. If you think you need to use eval, rethink what you are doing, especially for what appears to be a templating system.
