i trying send files client via jquery, ajax, , php. using jquery v1.11.2 , xampp v3.2.1,

here jquery code:

<script> $(document).ready(function(){     $("#mybtn").click(function(){         $.ajax({ // post file name             type: "post",             data: {                 file: "testfile.xlsx"                 },             url: "sendfile.php",             context: $("#result"),             success: function(data, status, xhr){                 $(this).html(data);             }         });     }); }); </script>

sendfile.php:

<?php  function send_file($name) { // function ... send file client   ob_end_clean();   $path = $name;  //cek connection if lost connection client   if (!is_file($path) or connection_status()!=0) return(false); //header //-------------------------------------------------------------   header("cache-control: no-store, no-cache, must-revalidate");   header("cache-control: post-check=0, pre-check=0", false);   header("pragma: no-cache");   header("expires: ".gmdate("d, d m y h:i:s", mktime(date("h")+2, date("i"), date("s"), date("m"), date("d"), date("y")))." gmt");  //set last modified property   header("last-modified: ".gmdate("d, d m y h:i:s")." gmt");   header("content-type: application/octet-stream");   header("content-length: ".(string)(filesize($path)));   header("content-disposition: inline; filename=$name"); // file   header("content-transfer-encoding: binary\n"); //-----------------------------------------------------------------   if ($file = fopen($path, 'rb')) { // send file    while(!feof($file) , (connection_status()==0)) {      print(fread($file, 1024*8));      flush();    }    fclose($file);   }   return((connection_status()==0) , !connection_aborted()); }  // send file if(!send_file($_post['file'])){     echo "error."; } 

when press button no files received instead of random sentences in #result

if use directly in php functions working properly

send_file("testfile.xlsx"); 

are there more effective methods?
