preg_replace out CSS comments?

Question

I\'m writing a quick preg_replace to strip comments from CSS. CSS comments usually have this syntax:

/* Development Classes*/
/* Un-comment me for easy testi

Just for fun(and small project of course) I made a non-regexp version of a such code (I hope it's faster):

function removeCommentFromCss( $textContent )
{
    $clearText = "";
    $charsInCss = strlen( $textContent );
    $searchForStart = true;
    for( $index = 0; $index < $charsInCss; $index++ )
    {
        if ( $searchForStart )
        {
            if ( $textContent[ $index ] == "/" && (( $index + 1 ) < $charsInCss ) && $textContent[ $index + 1 ] == "*" )
            {
                $searchForStart = false;
                continue;
            }
            else
            {
                $clearText .= $textContent[ $index ];
            }
        }
        else
        {
            if ( $textContent[ $index ] == "*" && (( $index + 1 ) < $charsInCss ) && $textContent[ $index + 1 ] == "/" )
            {
                $searchForStart = true;
                $index++;
                continue;
            }
        }
    }
    return $clearText;
}
