Auto updating the Client page

[Dheeraj Joshi]

Hi guys, I have got a question.

I have a client page .php and a php script to server that client page.

So can my php page in server can send the updated values for every 1 minute to client page?

I hope you understood my question.

well, I don't understand what you want to do with the php scripts, but you can use a cronjob to repeatedly execute something.

Server does not send anything to client spontaneously. It only "serves" requests from the client.

The client initiates all communication with a server. (Like in a restaurant: every restaurant server in the city doesn't come to your house without being asked)

Thus, your next question would be:

How do I make the client request every 60 seconds?

Now that's a better question. The answer? JavaScript !!

You can have JavaScript run something every set period of time. This could be an AJAX function or a function to reload the page (re-request the data from the server)

Want a head start?

// reload the page every 60 seconds
setTimeout(location.reload(), 60000);
 

Cheers,

If you're really keen on pushing data to the client from the server look up key words like: Reverse Ajax, Comet, Ajax Push, Full Duplex Ajax and Streaming Ajax. It's not an easy implementation and there are a lot of factors to consider so you may change your mind and stick with what Dlite922 recommended....

Dlite922's solution is much much easier to understand and implement :)

@dlite922
A better solution would be to update only a section of the page, using your suggestion of AJAX. Otherwise, you may be wasting bandwidth.
