अपनी पोल.php फ़ाइल के कोड को निम्न में बदलें:
<?php
include 'db.php';
$old_msg_id = $_GET['old_msg_id'];
$result = mysql_query("SELECT id FROM chatpoll ORDER BY id DESC LIMIT 1");
while($row = mysql_fetch_array($result))
{
$last_msg_id = $row['id'];
}
while($last_msg_id <= $old_msg_id)
{
usleep(1000);
clearstatcache();
$result = mysql_query("SELECT id FROM chatpoll ORDER BY id DESC LIMIT 1");
while($row = mysql_fetch_array($result))
{
$last_msg_id = $row['id'];
}
}
$response = array();
$response['msg'] = 'new';
$response['old_msg_id'] = $last_msg_id;
echo json_encode($response);
?>
