Problem with Export to Excel in PHP

I am having trouble with how the excel file looks once it gets exported. The exported excel file displays all the content in a single cell. In other words, all of the columns and rows in the MySQL table I am exporting just get dumped into a single excel cell. It seems that the "\t" and "\n" characters are simply being ignored during export. I am attaching the code I am using to generate the export. What am I doing wrong?

Not sure if this will help, but in my experience, when I want to export something to "Excel" I have had the best luck generating comma delimited values and writing to a .csv file.  If configured to do so (by default it is), Excel will open a .cdv file and you can go from there.  I don't know what to do about the \t and \n problem.  Hope that helps!

Nothing wrong, you have done...I really tried everything i can on your code but i cannot do with your way, but PEAR way...If you want, you can extract the functions from PEAR and use them as your need...

I scanned through your code once. I don't know what went wrong, but try to look at my working code below. This should give you some idea what to modify in order to make it working.
$csv_output = 'Last Name, First Name, User Name, Professor, Score, Submitted, ';
    $num_questions = getTotalQuestions();
    for ($i = 0; $i < $num_questions; $i++)
    {
        $csv_output .= ($i+1);
        if ($i != $num_questions - 1)
        {
            $csv_output .= ',';
        }
    }
    $csv_output .= "\015\012";
    $result = mysql_query("select * from students"); 
 
    while($row = mysql_fetch_array($result)) { 
        $csv_output .= "$row[last_name],$row[first_name],$row[user_name],".getProfLastName($row[prof_id]).",$row[score],$row[last_submitted],$row[answers]";
        $csv_output .="\015\012";
    }
 
    header("Content-type: application/vnd.ms-excel");
    header("Content-disposition: csv; filename= Student_Data_". date("Y-m-d") . ".csv");
    print $csv_output;
    exit;
