jquery PHP file upload causes browser memory usage to skyrocket -


i have jquery code:

$('input[type=file]').on('change', uploadfiles);   function uploadfiles(event) {     var data = new formdata();       var files = event.target.files;          for(var = 0;i<files.length;i++){         data.append("file_"+i, files[i]);     }        data.append('dir_name',current_directory);     apicall('upload.php','post',data,fileuploaded);  }

then in php file:

<?php $data = array(); $allfiles = scandir($_request['dir_name']); if(isset($_files)) {       $error = false;     $uploaddir = $_request['dir_name'];     foreach($_files $file)     {         echo $file['error'];         echo $file['tmp_name'];         $new_name = $file['name'];         move_uploaded_file($file['tmp_name'], $uploaddir .'/'.$file['name']);     } } else {     //some code here } echo json_encode($error); ?>

now works , everything, can upload file , multiple files @ time too. causes memory firefox uses skyrocket , never come down again. proportional file upload think, way way bigger. read in manual move_uploaded_file() deletes temporary file, can't problem. thing helps close firefox , open again. can please tell me why happens , how make stop?

if matters, using xampp test out on localhost.

this not happen in chrome.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
