timer...?

Anon

I need to create a timer in php that 'fires' every 94 seconds, and launch a new block of code? I don't want to use the html refresh as an option, is there any way to do this? I've been experimenting but haven't had any luck? Any suggestions?

Well since php is parsed on the server, you will probably have to resort to javascript, but you won't be able to break up php code to run every 94 sec. without reloading the page.

Is this to send new content to the user's browser, or just to execute periodically to update something on the server? If the latter, writing a script for use with crontab is the usual way to do such a thing. What's the server, and do you have complete shell access to it?

Hi Kirk,

No I don't have shell access, unfortunately, and the update is for the current page. I was wanting to display a new pic at various intervals, here's what i came up with so far....

<?php

$set = getdate();
$timerm=$set["minutes"];
$timers=$set["seconds"];
echo "minutes=$timerm"; //check output.
echo "seconds=$timers"; //check output.
print("$timer \n");
sleep(94);
$set = getdate();
$timer2m=$set["minutes"];
$timer2s=$set["seconds"];
if (($timerm+1 == $timer2m) && ($timers+34 == $timer2s)){
print("you da man!! \n"); //event to do here.
}
echo "timer2m=$timer2m, timer2s=$timer2s"; //just a check.
?>

It works in tests as is but am curious to test 'under fire'. Will check back and let you know.

And why is it a meta-refresh won't work for this? The method you are suggesting does work, but it has many limitations in regard to formatting--basically, if you're in the middle of a table or any other structure, the browser probably isn't going to render it. Thus you impose quite a few limitations on layout. But if you use meta-refresh, the browser simply get a complete new page each time.

A meta-refresh will work, but I was hoping to avoid it as there are other aspects of the page I don't want refreshed. A simple timer driven event handler...thats all...am i asking too much...sniff sniff....

Anon

Didn't work the way I hoped it would. 🙁

You'll need to use DHTML, I suspect, if you want only certain parts of the page to refresh.

hmmmm...more reading to do....grumble grumble..@$%&*#!

Alas, it is pretty orthagonal with the design of http, where the client expects to get the whole enchilada in one load from the server.

it as there are other aspects of the page I don't want refreshed

If you refresh them with the same contents they had before, is that good enough?

Anon

Not really...it's ok I'll try another approach. Alas the limitations ...the limitations!
