I'm creating a PHP script that interacts with the customer, slightly like Pandora Bot and Eliza. I want a time delay before "hello world" is printed to make it appear as if the computer is thinking/typing.

Any ideas would be great!

if ($response == ''){
//time delay goes here
print "hello world";
}

Thanks

Thanks for you response but there is no time delay no matter how high I set $n to be.

Is there any way I could use set timeout or anything else?

i don't think it really works with php. there are too many variables (i.e. server configuration, browser sensitivities) etc.

you could have auto-refreshing pages with an incremental counter and then use php to redisplay each page with new text based on the countervalue?

e.g put this code dynamically into the <head> tags of each page on generation. The 10 is the number of seconds and the URL is the next page you want displayed.

Code: 
<META HTTP-EQUIV="Refresh" CONTENT="10;URL=nextscreen.html">

to avoid the refresh look i'd seriously consider using javascript though. store the responses in a javascript var set (array?) and run a script that inserts the responses on predefined events like typing or time. lots of examples of this on the web.

Code: 
<?php

sleep(5);

echo "das";

?>

That should work. If it doesnt', then something is wrong with your server.

this does delay the script from the browser's perspective. but i have found that running php as an apache mod rather than a cgi means that
Code: 
<?
echo "hello";
sleep(10);
echo "hello world";
?>

does not insert the delay. i have a feeling it would do if php were running as a cgi.

have also tried variations with ob_start() and ob_flush() but it makes no difference (at least in my installation...)

Does the script take 10 seconds to come back to you ?

mmm interesting, the entire script is waiting 10 seconds before being sent, I'm suprised that the ob_* functions don't help here. When you get coundtown games they are usualy CGI with someting i think is called NPH (non parsed headers). I might be totaly wrong here my memory is not too good, could you replicate the proboem in perl, which I know should work.
Could you post a sample with your called to the ob_ functions in please

this isn't my chain, really...! but i guess we're still discussion brogan's initial query.

here's what i tried with the ob_flush calls:

Code: 
<?
ob_start();
echo "Hello World";
ob_flush();
sleep (20);
echo "Hellow World Again";
ob_end_flush();
?>

will have a go with perl when I have a mo.
