PHPExcel: won't read file, only when I first download it, put it in excel and put it back on the server -

so, our company have stock sync, every night our supplier put xlsx file on our server. worked great in beginning, discoverd sync broken.

the strange part here when download file computer , open excel en save file , upload on server, script read it...

so, when try read uploaded file won't work, when download file , open excel , save , upload on our server script read data fine.

anyone here has suggestion what's wrong ?

my code:

$lokaal_aanbodbestand="data/stocklistag_directly.xlsx"; //$lokaal_aanbodbestand="data/stocklistag_openedwithexcel.xlsx";  include("../../includes/phpexcel/iofactory.php");    $localsize = filesize ($lokaal_aanbodbestand);      try {         $inputfiletype = phpexcel_iofactory::identify($lokaal_aanbodbestand);         print $inputfiletype."<br />";         $objreader = phpexcel_iofactory::createreader($inputfiletype);         $objphpexcel = $objreader->load($lokaal_aanbodbestand);          $sheet = $objphpexcel->getsheet(0);          if(is_object($sheet)) {            $highestrow = $sheet->gethighestrow();           $highestcolumn = $sheet->gethighestcolumn();           print "amout of row: ".$highestrow."<br />amout of columns".$highestcolumn."<br /><br />";             //  loop through each row of worksheet in turn           ($row = 1; $row <= $highestrow; $row++) {               //  read row of data array               $rowdata = $sheet->rangetoarray('a' . $row . ':' . $highestcolumn . $row,               null, true, false);               foreach($rowdata[0] $k=>$v)                   echo "row: ".$row."- col: ".($k+1)." = ".$v."<br />";           }          }       } catch (exception $e) {         die('error loading file "' . pathinfo($inputfilename, pathinfo_basename)         . '": ' . $e->getmessage());     } ?>
