Answer 1

where you upload multiple file. you will get the files in array.
Therefore, you need to loop over the tmp files

function show_pdf_text($file){
  $pdf =  new PdfToText ($file) ;
  $text =  $pdf->Text; 
  echo $text;
}

if(isset($_POST['SubmitButton'])){
 if(is_array($_FILES['pdf_file']['tmp_name'])){
 foreach($_FILES['pdf_file']['tmp_name'] as $temp){
     show_pdf_text($temp);
  }
 }else show_pdf_text($_FILES['pdf_file']['tmp_name']);
}
