PHPExcell Cell coordinate can not be zero-length string

Question

I am using PHPExcel via the Zend framework and want to read entire Excel files into an array of data. I downloaded the final release from this page .

The code I am using is as below :

static function Read_Excel($inputFileName)
{
    $inputFileType = PHPExcel_IOFactory::identify($inputFileName);
    $objReader = PHPExcel_IOFactory::createReader($inputFileType);      
    $objReader->setReadDataOnly(true);
    $objPHPExcel = $objReader->load($inputFileName);    
    $objWorksheet = $objPHPExcel->setActiveSheetIndex(0);
    $highestRow = $objWorksheet->getHighestRow();
    $highestColumn = $objWorksheet->getHighestColumn();
    $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
    if($highestRow <=0 || $highestColumnIndex<=0)
        return false;
    $arr_data = array();
    for ($row = 1; $row <= $highestRow; $row ++) {
        for ($col = 0; $col <= $highestColumnIndex; $col ++) {
            $value = $objWorksheet->getCellByColumnAndRow($col, $row)->getValue();
            if (is_array($arr_data))
                $arr_data[$row - 1][$col] = $value;
        }
    }
    return $arr_data;
}

And I get this error:

 Message: Cell coordinate can not be zero-length string

I have searched a lot but found nothing! How can I resolve the problem ?

Answer 1

you definde cell is too short, you can add some cells like this:

$cell = array('A1','B1','C1','D1','E1','F1','G1','H1','I1','J1','K1','L1','M1','N1','O1','P1','Q1','R1','S1','T1','U1','V1','W1','X1','Y1','Z1');
