New Post: Cannot read an xlsx file

got same here.

i use yii framework .

i don't know why. everytime i try to read .xlsx it's always getting blank page .

if($original_extension == 'xls')
                {
                    $objReader = PHPExcel_IOFactory::createReader('Excel5');
                } elseif($original_extension == 'xlsx')
                {
                    $objReader = PHPExcel_IOFactory::createReader('Excel2007');
                }
                //$inputFileType = PHPExcel_IOFactory::identify($file);
                // $objReader = PHPExcel_IOFactory::createReader($inputFileType);
                $objReader->setReadDataOnly(true);
                $objPHPExcel = $objReader->load($file);
                $check=$objPHPExcel->getActiveSheet()->getCell('A1')->getValue();
                
                echo "<pre>";
                // var_dump($objPHPExcel);
                echo $check;
                echo "</pre>";

if i am insert xls file, i got the value . but when i am insert xlsx file. i got blank page .
thought PHPExcel_IOFactory can't read it . because when i use PHPExcel_IOFactory::indentify($file) it's got blank page too.

can someone help me what's going on here .
