Re: [PHP] Delaying Printed Output
Have you looked into javascript/java? This client has worked up a Power Point slide presentation that he wants me to duplicate on the web. I had a PHP solution that was working fine, but then he decided to jazz up his Power Point presentation some. The adding a single line of text at time didn't seem to complicated so I was going to see if I could find a PHP solution to it that would work with all browsers. But now he's decided that he wants motion involved with it too, so I guess I'll start learning a little more about FLASH. I did discover I have an Adobe program I have can use to create FLASH files so I guess I'll try that route and just warn him that he may be eliminating some web visitors this way (actually I'll probably keep the old PHP slide show and give them an option). Thanks everyone for your input into this.

RE: [PHP] Delaying Printed Output
This topic comes up from time to time...
Some previous information, if you get any further please post it to the list.
A while ago I saw a web page explaining a system (written in Perl I
think) that was used to show a presentation to a number of different
sites simultaneously (and synchronised). A presenter was at the main
site and the browsers at 4 other remote sites would display the same
page the presenter was viewing on his web browser as he went to various
sites. I think it worked using multipart Content-type.
Unfortunately I have lost the URL to the explanation of how it was
done.
On Saturday, 5 August 2000 8:48 AM Mr Bruce Christensen posted the following links
explaining browser push;
http://home.netscape.com/assist/net_sites/pushpull.html
and;
As for keeping the connection from timing out, see
http://www.php.net/manual/function.set-time-limit.php.
I have experimented with this but didn't get too far. I posted the following to the
PHP list but didn't get any reply.
I have tried the following script on
WinNT5, Apache/1.3.13-dev, PHP Version 4.0.1pl2
and
OpenBSD2.7 Apache/1.3.12, PHP Version 4.0.1pl2 (mod_php4)
push.php;
--8---snip---8--start
?php
header("HTTP/1.0 200 OK");
header("Content-type:
multipart/x-mixed-replace;boundary=ThisRandomString");
print("\n");
print( "--ThisRandomString\n");
print("Content-type: text/html\n");
print("\n");
print( "First update at ");
echo date("H:i:s");
print("\n\n");
print( "--ThisRandomString\n");
flush();
sleep(5);
print("Content-type: text/html\n");
print("\n");
print( "Second update at ");
echo date("H:i:s");
print("\n\n");
print("--ThisRandomString--\n");
?
--8---snip---8--end
On NT with the
header("HTTP/1.0 200 OK");
statement I get an Apache error message;
[Sun Aug 06 09:02:47 2000] [error] [client 192.168.0.60] malformed
header from script. Bad header=HTTP/1.0 200 OK: f:/program files
/novato/allcnet/php.exe
I do not get this error on OpenBSD.
I then removed the
header("HTTP/1.0 200 OK");
statement and now NT and OpenBSD give the following output
to the browser(IE5.0);
(after a 5 second pause)
--8---snip---8--start
--ThisRandomString
Content-type: text/html
First update at 18:22:47
--ThisRandomString
Content-type: text/html
Second update at 18:22:52
--ThisRandomString
--8---snip---8--end
And the following output to the browser(Netscape 4.6);
(after a 5 second pause)
--8---snip---8--start
Second update at 18:23:19
--8---snip---8--end
ie With Netscape I never see the
first update at ...
part of the output as I would expect.
I have also tried it with;
header("Content-type: multipart/mixed;boundary=ThisRandomString");
but it makes no difference, the behaviour is identical.
IE5 does not seem to understand multipart.
The multipart mime boundary does not seem to be working properly in
Netscape4.6.

You might try using flush() after the prints.
I tried that too, but at least in Netscape 6, it still waits until
everything is done before displaying. I think Jack must be correct that
this isn't possible for browser display.

[PHP] Delaying Printed Output
Is it possible using PHP to print a single line of text to a browser, have a second or two delay and then print the next line, etc. etc.?

Re: [PHP] Delaying Printed Output
You can use the following commands: sleep(seconds); usleep(microseconds); I've tried those 2 functions, in an example like this: PRINT "Thisbr"; SLEEP(2) ; PRINT "Is abr"; SLEEP(2); PRINT "TEST"; But the way it works in the browser is to wait for a total of 4 seconds and then it displays all the text at once, not one line at a time - which is what I'm after.

RE: [PHP] Delaying Printed Output
I may be wrong about this, but I'm pretty sure that, being server side, PHP sends the HTML to the browser all at once...also, the browser needs a static HTML page to load up...it can't take a line and output as it goes...maybe i'm wrong, but i thought that was basically how it works, so you couldn't do the sleep thing you wanted... anyone else? jack -Original Message- From: Greg Scott [mailto:[EMAIL PROTECTED]] Sent: Saturday, March 24, 2001 1:42 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: [PHP] Delaying Printed Output You can use the following commands: sleep(seconds); usleep(microseconds); I've tried those 2 functions, in an example like this: PRINT "Thisbr"; SLEEP(2) ; PRINT "Is abr"; SLEEP(2); PRINT "TEST"; But the way it works in the browser is to wait for a total of 4 seconds and then it displays all the text at once, not one line at a time - which is what I'm after.

Re: [PHP] Delaying Printed Output
Speaking off the top of my head, seems like a combination of html meta refresh and a variable that increments based on HTTP REFERRER=PHP_SELF could provide the effect you're looking for. Certainly you could meta refresh to new pages in sequence. Or of course just use an animated gif if static text. Have you looked into javascript/java? I doubt that you can do it solely within php as it parses once and delivers html. The connection betwixt the server and client is transaction and the client would have to initiate the call to update, unless the update was imbedded within and staged at the client.

By any chance is this within a table? Not sure what v.6 expects, but at least in earlier versions Netscape refused to show table content until it encountered the closing /table tag. With the end result that flush() appears not to be working, when actually PHP is doing its job fine but NN is being a bit of a PITA. -- CC -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
