cant upload file using phpexcel

i am currently using phpexcel library to read my excel file which is to be uploaded by user . but i cannot at this moment :(

i am using this code, i cannot开发者_StackOverflow社区 get the file path right at this moment and if some one could tell me , how to over ride existing file and renaming the input file.

  move_uploaded_file($_FILES["file"]["tmp_name"],
  "upload/" . $_FILES["file"]["name"]);
  $test= $_FILES["file"]["name"];
  echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
  require_once('classes/phpexcel.php');
  $objReader = PHPExcel_IOFactory::createReader('Excel2007');
  $objReader->setReadDataOnly(true);
  $objPHPExcel = $objReader->load('upload/'.$test);
  $objWorksheet = $objPHPExcel->setActiveSheetIndex('0') ;

kindly help and thanks in advance

File is being transferred to the desired folder , i cannot open the file with phpexcel

I'd sanitize the destination file name on the move_uploaded_file. use something like tempnam() to generate a safe file name
