it is about a for loop problem

for ($row = 1; $row <= $highestRow; $row++) {
    echo "<tr>";
    for ($column = 0; $column < $highestColumn; $column++) {
        $val = $sheet->getCellByColumnAndRow($column, $row)->getValue();
        echo "<td>";
        //echo $val;
        echo $row,$column;
        echo "</td>";
  }
  echo "</tr>";
}

the highest row and highestcolumn are both are 4 in this case

    Too big for a comment:

    Try changing

    $highestRow = $sheet->getHighestRow(); 
$highestColumn = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn());

    to

    $highestRow = $sheet->getHighestRow(); 
$highestColumn = $sheet->getHighestColumn(); 
$highestColumn++;

    and

    for ($head = 0; $head < $highestColumn; $head++){  
    echo "<th field='col' $head> Unname coloum $head </th>";  
}

    to

    for ($head = 'A'; $head !== $highestColumn; $head++){  
    echo "<th field='col' $head> Unname coloum $head </th>";  
}

    and

    for ($column = 0; $column < $highestColumn; $column++) {        
    $val = $sheet->getCellByColumnAndRow($column, $row)->getValue();        
    echo "<td>";        
    //echo $val;        
    echo "$row,$column";        
    echo "</td>";        
}

    to

    for ($column = 'A'; $column !== $highestColumn; $column++) {     
    // $val = $sheet->getCellByColumnAndRow($column, $row)->getValue();     
    echo "<td>";     
    //echo $val;     
    echo $row , $column;     
    echo "</td>";     
}

    Note that I’ve commented out the getCell call for the moment
