phpExcel reader long numbers to text -

when reading excel file, have problems numbers greater length:

i use:

try {     $inputfiletype = phpexcel_iofactory::identify($inputfilename);     $objreader = phpexcel_iofactory::createreader($inputfiletype);     $objphpexcel = $objreader->load($inputfilename); } catch(exception $e) {     die('error loading file "'.pathinfo($inputfilename,pathinfo_basename).'": '.$e->getmessage()); } $sheet      = $objphpexcel->getsheet(0);  $highestrow     = $sheet->gethighestrow();  $highestcolumn  = $sheet->gethighestcolumn();  ($row = 1; $row <= $highestrow; $row++){    $obj = $sheet->rangetoarray('a' . $row . ':' . $highestcolumn . $row, null, true, false);   list($code, $name) = $obj[0];   echo $code; } 

and returns 1.6364698338384e+18

is possible obtain 1636469833838380000 ?

i try

$code = (string) floatval($code); 

... nothing...

you can change cell format text in excel file , try reading values it.

hope helps.
