[PHP] Variable Undefined, even when global?

[Ron Biggs]

I'm getting a "Variable Undefined" error, even tho phpinfo() shows me that
globals are set to ON.  I've done massive searches on the web to find a
solution, but I'm totally missing it.  Help?  (I've bolded where the
Variable Undefined is occuring --- where <<$whatglass =
$lkColor[$i]->glass;>> is written.)

Here's the code:

==code start=
code = $code;
  $this->name = $name;
  $this->glass = $glass;
 }
}

// $lkColor = array(dbColors($code,$name,$glass));
 $lkColor[0] = new dbColors;
 $lkColor[0]->dbColors("Z651","Red","9");

 $lkColor[1] = new dbColors;
 $lkColor[1]->dbColors("R3","Cranberry","8,9");
//rest are clipped

 define("test", count($lkColor));
// global test =  count($lkColor);

function ColorCollection($lkID){

 $whatX = $lkID + 1; // Adding 1 turns makes the index correspond to the
template number.

// $aColLen = count($lkColor); //.length
 $aColLen = test; //sizeof($lkColor); //.length

 echo "xxx\n"; //first option is blank

// KeepGoing: //PHP does not have a line-label statement.  Set up a trigger
 for($i=0;$i<$aColLen;$i++){
  $trigger = false;
  $whatglass = $lkColor[$i]->glass; //shouldn't $lkColor[any-number] be
global??? <<<
  // collect/build the option

  //if $lkID = egg or ornament (template numbers 8 or 9)
  if($whatX == 8 || $whatX == 9){ // if yes to either
   if($whatX == 8){
$pos = strpos($whatglass,"8");
if($pos === true){
 echo "code}\">{$lkColor[$i]->name}\n";
 //continue KeepGoing;
 $trigger=true;
 continue;
}
}
   if($whatX == 9){
$pos = strpos($whatglass,"9");
if($pos === true){
 echo "code . "\">" .
$lkColor[$i]->name . "\n";
 //continue KeepGoing;
 $trigger=true;
 continue;
}
   }
  }else{
   if($trigger == false){
echo "code . "\">" .
$lkColor[$i]->name . "\n";
continue;
   }
} //EndIf either 8 or 9
  } // FOR colors loop
} // end function
?>

==code end==

I'm calling the function this way:


   



How can $lkColor[$i]->glass not be global?
