Hi All,

I noticed that in the snapshot page<http://windows.php.net/snapshots/>, we have 
a VC9 x64 Thread Safe binaries. However it's not intended for production use.
So my question is, when can we get the official x64 PHP binaries? What's your 
schedule?

Thanks very much!

--- Begin Message --- The main issue with these systems is updating the client on a regular enough basis. If the content is time critical, like with Facebook chat, then you need to do long polling.

However for a Shoutbox, because it's more like an IRC channel with people 'shouting' to a channel, you can probably just set the client to automatically update on a regular basis. Or even more advanced, would be to get it to check in increasing intervals. Firstly it checks 0.5s later, then 1s later, then 2s, 4s, 8s, 16s, with a limit of 60s (i.e it checks at least once a minute for an update), upon new content being received the time is reset back to the 0.5s

If you need to do long polling <http://ajaxpatterns.org/HTTP_Streaming> then look into the Tornado Webserver <http://www.tornadoweb.org/> which Friendfeed <http://friendfeed.com/>, and more recently, Facebook use (for their LiveFeed system). For a PHP based implementation check this out <http://www.zeitoun.net/articles/comet_and_php/start>.

I don't know of anything you can use like this, especially that runs

fails and falls over on a constant basis to the point where it is almost
useless. Imho, Java seems to be pretty good at this sort of thing, and
there are plenty of free options out there that you could use.

It's often been argued back and forth whether people have Javascript
turned off. I suspect the vast majority of people have Javascript turned
on. However, Java is another story. You may find that many more have it
turned off.

Yeah, but then, generally, you can tell the people visiting this site
what they need enabled, as it looks like the visitors are going to be a
select few. Java is available on all the main browsers, and generally
only needs one to accept the applet. For a chat application to be
written using only Ajax technology, well, like I said before, if
Facebook tried it and still can't get it right with all the financial
backing they have, what hope for someone to release this sort of thing
open source and Facebook not be aware of it?

If $_POST['showid'] is likely to be an array, use implode to create a comma
separated string of values, then use IN to build the query.

$ids = implode(',', $_POST['showid'];
$subSQL = "SELECT order_id FROM afy_show_lineitem WHERE show_id IN ($ids)"

But you need also to check your logic - your query above will have two WHERE
in it and will fail miserably :-) And your call to mysql_error will
probably not help you either, as the (optional) argument should be a link
identifier, not a string of your choosing.

$subResult is a resource. You need to fetch the results
before you can use them like this. Maybe something like:

--------------------
  /* UNTESTED */

  /* Don't forget to escape! Some will argue that
     you are better off using prepared statements. */
  $showid = mysql_real_escape_string ($_POST['showid']);

  $q = <<<_
SELECT `order_id` FROM `afy_show_lineitem`
 WHERE `show_id` = '$showid';
_;

  $res = mysql_query ($q);
  if ($res) {
    while ($row = mysql_fetch_row ($res)) {
      $ids[] = $row[0]; /* Assuming numerical ids. */
    }
    $ids_spec = implode (',', $ids);
    mysql_free_result ($res);
  } else {
    /* Handle error */
  }

  if (isset ($ids_spec)) {
    $q = <<<_
SELECT * FROM `afy_order`
 WHERE `order_id` IN ($ids_spec)
_;
    $res = mysql_query ($q);
    if ($res) {
      /* Do stuff */
    } else {
      /* Handle error */
    }
  }
--------------------

But you could also do it in one query (*untested*):

  /* UNTESTED */

  SELECT `ao`.* FROM `afy_order`         AS `ao`,
                     `afy_show_lineitem` AS `asl`
   WHERE  `ao`.`show_id`  =  $show_id
     AND `asl`.`order_id` = `ao`.`show_id`


Or maybe there are better ways, such as using INNER JOIN,
but those sometimes end up using a temporary table...

I'm not even sure this is possible, and if it is, you know it would only
work on Internet Explorer yeah?

If the dll is in the server, you could potentially call the server via Ajax to instantiate the dll and have it's output sent to the browser

usually .dll should be running client side not server side

jscript and javascript are two different beasts based on ecmascript;
you'll be wanting to get some JScript (microsofts own version) help for
this.. http://msdn.microsoft.com/en-us/library/7sw4ddf8%28VS.85%29.aspx
but as somebody else mentioned, you won't get it working on all browsers
AFAIK.. so running DLL on server side and calling wrapper functions via
ajax is more appropriate.

an asp.net forum or suchlike will probably yield a more useful response

ur... you mean use this in the php script?
but the php-cgi still doesn't know which scriptfile to execute, isn't it?

php-cgi tries to find the aimed script using SCRIPT_FILENAME, but this
variable is changed by the mod_proxy_fcgi, so php-cgi can not find the real
scriptfile, that's the point, I think.

Or maybe there is something I misunderstand?

Hi,
I am not getting what are you asking but if you want to run two httpd then
you have to run those on different ports.
For this you can change "Listen 80" to "Listen 2020" from httpd.conf file.
So that one server will run on 80 and other will run on 2020.
you can change 2020 to whatever port you want .. but check if that port is
not already assigned to some other application.

There is another httpd instance running on the same host. If I run httpd

it be a separate process?

note: setting only the same instance to listen on port 2020 or suchlike
as well won't help you here, you need 2 instances
