[Resolved] declaring global w/in a class

[perpetualshaun]

I'm relatively now to OOP, and I'm trying to write a class that I can pass values to which whill display a listing table of results from a MySQL table.

Another thing that I'd like to do is pass an array of values to the class, and then when I'm displaying all the results, enclose the values I pull from MySQL inside of that I passed in another function. Since the array titles and values will be different every time, I'd like to declare them as globals. Here's part of my class:

class listingTable {

// defining the variables that will be used to build the form and table
var $row_values = array();

function defineVars($define_row_values) {
	if($define_row_values != "") $this -> row_values = $define_row_values;
}
function declareVars($var_array) {
	while($each = each($var_array)) {
		global ${$each["key"]};
		${$each["key"]} = $each["value"];
	}
}

function buildFormAndTable() {

	echo "\n<a name=\"results\"></a>\n";
	echo "<table cellspacing=\"0\" cellpadding=\"5\" class=\"listing_table\">\n";

	// printing the table rows
	while($value_array = mysql_fetch_array($this -> result)) {
		if(isset($bgc) && $bgc == "bg1") {
			$bgc = "bg2";
		} else {
			$bgc = "bg1";
		}
		echo "<tr class=\"".$bgc."\">\n";
		echo "\t<td nowrap=\"nowrap\">\n";
		if($value_array[$this -> row_values[$each["key"]]["field_name"]] != "") {
			if($this -> row_values[$each["key"]]["type"] == "result_value") {
				if(isset($this -> row_values[$each["key"]]["format"]) && $this -> row_values[$each["key"]]["format"] == "ucwords") {
					echo htmlentities(ucwords($value_array[$this -> row_values[$each["key"]]["field_name"]]));
				} elseif(isset($this -> row_values[$each["key"]]["array_val"])) {
					print_r(${$this -> row_values[$each["key"]]["array_val"]});
					//echo htmlentities(${$this -> row_values[$each["key"]]["array_val"]}[$value_array[$this -> row_values[$each["key"]]["field_name"]]]);
				} else {
					echo htmlentities($value_array[$this -> row_values[$each["key"]]["field_name"]]);
				}
			}
		} else {
			echo "&nbsp;";
		}
		echo "</td>\n";
		echo "</tr>\n";
	}
	echo "</table>\n";
}
}

And then here's what I'm passing to it, w/ my $item_category_array defined earlier on the page:

$listing_table = new listingTable();

$table_header["item_category"] = "Category";

$row_values["item_category"]["field_name"] = "item_category";
$row_values["item_category"]["type"] = "result_value";
$row_values["item_category"]["array_val"] = "item_category_array";

$listing_table -> defineVars($row_values);
$listing_table -> declareVars(array("item_category_array" => $item_category_array));
$listing_table -> buildFormAndTable();

So why isn't that available as a global variable in the buildFormAndTable functions? Any ideas?
