所有单元格都像PHP Excel一样

I'm trying to read some data from excel file. Everything is good if i have ex.50.44% in my excel cell PHP excel format it like float 0.0531 i dont want to format any numbers and i want all cell to be casted as string. How can i accomplish this before making the data toArray();

Here my sample code

try {
    $objPHPExcel = PHPExcel_IOFactory::load($upload_url);
} catch(Exception $e) {
    die('Error loading file "'.pathinfo($upload_url,PATHINFO_BASENAME).'": '.$e->getMessage());
}

 $objPHPExcel->getDefaultStyle()
->getNumberFormat()
->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_TEXT);


$sheetData = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
var_dump($sheetData);
exit;

Any help will be appreacited.

If you simply want all values as strings rather than the appropriate datatype, then retrieve your array as you're doing at the moment, then execute:

array_walk_recursive(
    $sheetData,
    function (&$value) {
        $value = (string) $value;
    }
);
