ajax - apc_fetch PHP 5.3 with Zend Server -


i encountered problem when wanted show process bar in file upload.

my php version 5.3.14. zend server version 5.6. turned off zend data cache & zend optimizer+.

<?php $uiq = uniqid(); $image_folder = "uploads/"; $uploaded = false;  if(isset($_post['upload_image'])){      if($_files['userimage']['error'] == 0 ){         $up = move_uploaded_file($_files['userimage']['tmp_name'],     $image_folder.$_files['userimage']['name']);         if($up){            $uploaded = true;            }     }  } ?>

following process code called ajax.

if(isset($_get['progress_key']) , !empty($_get['progress_key'])){      $status = apc_fetch('upload_'.$_get['progress_key']);     if($status){         echo $status['current']/$status['total']*100;     }else{         echo 0;     }   exit; }
