Simple iteration question

[qwerty234]

Ignoring the print_r below (which is telling me that there is data in $result), can someone tell me why my iteration is not outputing the data from $result?

 

        
        $excel_row = 6;
        $excel_col = 0;
        
print_r($result);

        $colnames = array_keys ($result[0]);

        foreach ($result as $row)         
        {
    foreach ($colnames as $colName)
           {
       $sheet->write($excel_row,$excel_col,$row[$colName],$colHeadingFormat);
              $excel_col++;
           }           
           $excel_row++;
        }

Can we see what print_r($result) shows you?
