php - How to get more than 1 ajax call response in different intervals? -

-

as i'm doing ajax call need show in front end what's running in end.

for example, i'm uploading file. @ time have following steps complete.

  1. inserting file data db
  2. moving of files folder, based on response step 1
  3. finally updating db

through single ajax

  • while step 1 running need show : inserting files db...
  • in step 2: moving files folder...
  • in step 3: updating table...

i know how 3 responses @ time 

json_array('res1' => '', 'res2' => '', 'res3' => '')

but need same responses 3 intervals. below code understand

function file_sampe_upload(){     //code insert     .......     echo json_array('status' => 1, 'res1' => 'files inserted successfully');    //code moving files specific folder    ......    echo json_array('status' => 1, 'res2' => 'files moved successfully');    //code updating files    ......    echo json_array('status' => 1, 'res3' => 'files updated successfully'); exit;}

is there possibility this? advise helpful.

update:-

is concept outputbuffering full, issue?

you need perform 3 ajax requests this. this:

function file_sampe_insert(){     echo json_array('status' => 1, 'res1' => 'files inserted successfully');     exit; }  function file_sampe_move(){     echo json_array('status' => 1, 'res2' => 'files moved successfully');     exit; }  function file_sampe_upload(){    echo json_array('status' => 1, 'res3' => 'files updated successfully');     exit; }  1. ajax request call insert  2. ajax request call move 3. ajax request call upload
