PHPExcel excel读取不适用于某些计算单元格

Question

I use PHPExcel lib for read the excel file in Codeigniter project. It is not read some cells with calculation. It show as #VALUE! But some values with calculation is reading in same excel sheet. Whats wrong with those cells?

Cells with have following calculation is not reading

=+D109*1000     
=+B16/B13
=+D23/$D$109 

Cells with have following calculation is reading

=+B10-B11
=+C10-C11

But all cells are reading for some excel sheet. This issue come with xlsx format

This is my code

$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objReader->setReadDataOnly(true);
$this->excel = $objReader->load($path);
$this->excel->setActiveSheetIndex($sheet);
$data = $this->excel->getActiveSheet()->toArray(null, true, true, true);

print_r($data);

I check with google. getCalculatedValue() should use for read calculated values. But i can't use it one by one. Is it has a method to read all sheet as array?

How ever i checked some cells with following way

$this->excel->getActiveSheet()->getCell('B18')->getCalculatedValue() // return #VALUE!
$this->excel->getActiveSheet()->getCell('B18')->getOldCalculatedValue() //return 0.4211

How i use old calculated value using toArray?

Answer 1

Finally I get old getOldCalculatedValue using loop.

$data = $this->excel->getActiveSheet()->toArray(null, true, true, true);

//This code add for some calculated cells were not reading in xlsx format
foreach ($data as $no => $row) {
    foreach ($row as $key => $value) {
        if (isset($value) && $value == '#VALUE!') {
            $data[$no][$key] = $this->excel->getActiveSheet()->getCell($key.$no)->getOldCalculatedValue();
        }
    }
}
