It was necessary to chat about this technology, everything seems to be usually updated on the example of the file, but how to update the query?
`set_time_limit(0);
while (true) {
$data_source_file = R::findLast('messages', 'dialog = ? ',array($_GET['getmess']));
$last_ajax_call = isset($_GET['timestamp']) ? (int)$_GET['timestamp'] : null;
clearstatcache();
$last_change_in_data_file = $data_source_file->date;
if ($last_ajax_call == null || $last_change_in_data_file > $last_ajax_call) {
$data = $data_source_file->message;
$result = array(
'data_from_file' => $data,
'timestamp' => $last_change_in_data_file
);
$json = json_encode($result);
echo $json;
break;

} else {
    sleep(1);
    continue;
}

}`

Well, roughly, the date of the last message looks like this $data_source_file->date;

Do you have a sugestion to how the script can reconnect when network connection is disconnected, and then eventually reconnected.

Tested system: ubuntu/arch linux + apache

step:
copy index.html to client.php ( only php file can reproduce )

I can't refresh client/client.php at second time when session.auto_start=1 in php.ini

I resolve it after add session_write_close() or session_commit() in server.php

relative issue:

I'm glad you read my report. Sorry for my poor English.

Hi!
Can someone help me?
When data.txt change I want to reload the client.html page (instead of changing the "response" div content).

I've tryed also something like this (so i can use php to reload page or other things)

$('#response').html(" ");

but the string "hello world" is never displayed (of course, i've renamed the client.html in client.php)

Any help is really appreciated.

Since you are sending the previous modification time in every Ajax request but the first, why not have the PHP code echo the message, then die()?

If changes are missed, you could put the sleep() call in the code that writes the file content rather than in your loop.

I am using wamp server to run your example. If I open your example by: enter 127.0.0.1, then go to Your Projects > php-ajax-long-polling-master, your example run effectly. But if I click on index.html directly to open it on browser, the example not working. Are there anyway to solve this problem? Because I'm using jquery mobile and phonegap, my website files are on client, not on server. Look forward to hear from you. Thank you!
