What about parameter passing and parameter reference?

Parameter passing and parameter reference problem??
I have a flash player, introduced into a PHP page with an OBJECT tag, passed in the parameter to the PHP page, and then used $_get["" "to get the incoming parameters, and then put the passed parameters into a string, as a value inside the Param, but in any case can not be implemented. I am the first time to contact PHP this thing, please experts to teach you, thank you

$val = "mp3= $filename &showtop= $showtop &showinfo= $showinfo &showvolume= $showvolume";
return $val;
}
?>
