[PHP] Switch Question

[Van Andel, Robbert]

I'm trying to make a switch statement that looks for more than one possible value.  
Something similar to:
 
switch($color)
 {
  case "black" || "1":
   return ImageColorAllocate($image,0,0,0); 
   break;
  case "white" || "2":
   return ImageColorAllocate($image,255,255,255);
   break;
  case "gray" || "3":
   return ImageColorAllocate($image,200,200,200); 
   break;
}
 
This is not working however, since all my colors are now black (it worked before I add 
the number portion of the case statement.
 
First off, is this even possible to do, or do I need to make a seperate case for the 
numbers.  If it is possible, how do I make it work?
