javascript - XMLHttpRequestProgressEvent manipulation from PHP -

i'm struggling issue: have web interface connects, using sockets, various c programs running on routerboards. every time c application sends through socket, php application receives it. works one-shot requests, there 1 case need update interface on browser each time c application sends update, until ends task. can start process using jquery.ajax call php script handles communication c application, , i've managed send xmlhttprequestprogressevent client after each update writing php output buffer , flushing every time script receives through socket has open towards c application. thing is, i'd add meaningful data xmlhttprequestprogressevent, , can see inspecting it has both target , srctarget properties xmlhttprequests. thought responsetext 1 of content of buffer, it's not.

so question is: how can encapsulate data inside xmlhttprequestprogressevent php , , there better way using flush send event?

some code:

c

pipe = popen(command, "r");  while(!feof(pipe)) { if(fgets(buffer, 128, pipe) != null)     printf("%s\n", buffer);     tcp_send(currenthandler, buffer); }  pclose(pipe); 

(yes, execute process , send output, @ least now).

php

$done = false;  while(!$done) { $buffer = socket_read($socket, 128);  if (!$buffer || $buffer == "")     $done = true;          // i'd send value of $buffer well!      echo ".";     flush(); } 

javascript

$.ajax({     url: 'myscript.php',     type: 'post',     datatype: 'json',     data: {action: 'runtest', ajax: true},     success: function(data, status, xhr) {         console.log('aye!');     },     progress: function(e) {         console.log(e);     },     error: function(xhr) {         console.log('nay!');         console.log(xhr);     } }); 

(of course extended jquery.ajax handle progress event)

update according w3c specification progress event can have lengthcomputable, total , loaded values. fair enough. i'd still able set respective values :)

try node.js maybe can useful you
