Reading a XLSX sheet to feed a MySQL table using PHPExcel

Question

I found the PHPExcel library brilliant to manipulate Excel files with PHP (read, write, and so on).

But nowhere in the documentation is explained how to read

Answer 1

Here is the code

$inputFileName = $upload_path . $filename;
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load($inputFileName);
$objWorksheet = $objPHPExcel->getActiveSheet();

$highestRow = $objWorksheet->getHighestRow();
$highestColumn = $objWorksheet->getHighestColumn();
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
$rows = array();
for ($row = 1; $row <= $highestRow; ++$row) {
  for ($col = 0; $col <= $highestColumnIndex; ++$col) {
    $rows[$col] = $objWorksheet->getCellByColumnAndRow($col, $row)->getValue();
  }
  mysql_query("INSERT INTO upload (`item_number`,`qty_sold`,`cost_home`) VALUES ($rows[1],$rows[2],$rows[3])");
}

?>

I have tried mysql_query("INSERT INTO upload (col1,col2) VALUES ($rows[1],$rows[2])"); as well but didn't work. The table stays empty
