I would like to know if there is Timer function available in PHP in order to execute part of my code every X time. If not how can i do it?

Do you have any sample code?

All servers have timers that will allow the to rerun pieces of code against a schedule. On Wiundows, this is known as a Scheduled Task, and on Unix, it's a cron job.

This is if you really just want the code to run at a set interval on the server - without any user intervention. (I say this, because sometime people ask this question on groups and lists, when all they really mean is that they want a page to refresh itself evey so often in a user's browser.)

Does that help at all?

This is what i mean... a page that is being refreshed by itself without any condition. The problem is that i dont know how to implement this and The books I have don't refer something similar to this! Please Help!

Well, in that case, you probably haven't found it in a PHP book because it's actually a HTML problem :).

Since page requests have to be made by the client, and cannot result from any action by the server (i.e. the web isn't a "push" technology", as they are still sometimes called), you have to instruct the browser to re-request the page every so often.

Put something like this in your page header:

<meta http-equiv="refresh" content="30;URL=your_page.php" />

That'll cause the browser to make a new request for the page, every 30 seconds (hence the number "30" in the content atribute). This will continue every 30 seconds for as long as the page remains open in the browser window. Be careful about this, though, since it can be very annoying to users on slow connections, who may never get a complete copy of the page before their browser makes a new request for it, and thus end up constantly looking at a part-completed page.
