Your script is ending, so the page ends. PHP (HTTP) isn't really
supposed to do "streaming." If you want it to "stream" you have to
keep the script running. Add something like this:
while(true) {
while($db->next_record()) {
echo '<b>'.$db->Record["user"].':</b> ';
$sql = "SELECT emote, image FROM c_emotes";
$result = mysql_query($sql, $db->linkid);
while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
$emotes[] = $row['emote'];
$images[] = "<img src='".$row['image']."'>";
}
if($db->Record['system'] != 1) {
$message = htmlentities($db->Record["text"]);
} else {
$message = $db->Record["text"];
}
$message = str_replace($emotes, $images, $message);
echo $message."<br>\n";
flush();
}
sleep(5);
set_time_limit(30);
}
This will actually run *forever* and will loop through the records
again and again, probably giving yu the same content as before. You
would need some kind of way to know which records are "new" so you can
only display them in the loop. I would suggest adding a "time >
$savedTime" or some such to the loop.
Please note, though, that this is a *very large hack*. You're not
supposed to keep your scripts running forever. If you really want to
"stream", write a Java/C/C++/C#/etc. app. Or, if you're feeling
adventurous, use JavaScript.
