 $allowed_extension = array("xls", "xlsx", "csv"); //allowed extension
 if(in_array($extension, $allowed_extension)) //check selected file extension is present in allowed extension array
 {
  $file = $_FILES["excel"]["tmp_name"]; // getting temporary source of excel file
  include("PHPExcel/Classes/PHPExcel/IOFactory.php"); // Add PHPExcel Library in this code
  $objPHPExcel = PHPExcel_IOFactory::load($file); // create object of PHPExcel library by using load() method and in load method define path of selected file

这里看起来像是一个查询输入错误：

“$arabic\u summary.”、“$english\u summary.”

mysqli\u error（）

，查看查询返回的任何错误。
