Foreach on 2D Array Doesn't Produce Output - php

Question

I have a function inside a PHP class that reads as follows:
//properties
var $title;
var $thePage;
function gBuildTable($theArray){
//given a 2D array, builds an HTML table based on that array
$table = "<table> \n";
foreach ($theArray as $row){
$table .= "<tr> \n";
foreach ($row as $cell){
$table .= " <td>$cell</td> \n";
} // end foreach
$table .= "</tr> \n";
} // end foreach
$table .= "</table> \n";
return $table;
} // end gBuildTable
function buildTable($theArray){
$temp = $this->gBuildTable($theArray);
$this->addText($temp);
} // end buildTable
function addText($content){
//given any text (including HTML markup)
//adds the text to the page
$this->thePage .= $content;
$this->thePage .= "\n";
} // end addText
function gAddText($content){
//given any text (including HTML markup)
//returns the text
$temp= $content;
$temp .= "\n";
return $temp;
} // end addText
So then I have a bunch of data which I build into a 2D array as such (hopefully its correct structure):
$data = array(
array("Name", $name),
array("Email", $email),
array("Hobby", $hobby),
array("", $stamp)
);
$obj = &New sH; //the class name
$obj->buildTable($data);
Am I making some boneheaded oversight or something that I am not seeing? This doesn't produce anything, it LITERALLY comes back empty. No errors, No warning, No notices, NADA.
FYI: The variables such as $name have all been previously initialized and set, they are NOT NULL. Any assistance as to what I am doing wrong, would be greatly appreciated. TIA
PS. I used current() inside the foreach loop to echo out what it is seeing at that time, and it sees the data, so I am at a loss why its not actually doing anything.
Update [SOVLED]
I can't believe I missed it and no one else caught it, but its OK, part of the wonderful world that is coding. I resolved it by noticing that its missing ONE line to grab the internal object that is being built:
echo $obj->$thePage;

You need to echo $table; in your function..!
or store the value the function is returning and echo in your main code.
$data = array(
array("Name", $name),
array("Email", $email),
array("Hobby", $hobby),
array("", $stamp)
);
$obj = &New sH; //the class name
$table = $obj->buildTable($data);
echo $table;
