does php have interval/timeout capabilities

[dsdsdsdsd]

 

hello;

 

javascript and actionscript both have set_interval type of functions, such as:

var my_interval = setTimeout( a_function , number_of_milliseconds , my_argument_list )

 

 

does php have something similar;

 

I have come across 'curl' functions, though I am not certain if my php ( and my webhost's ) has the curl extension, so I am hoping that php has something more naturally inherent;

 

thanks

why would u need php to take a timeout?

There are sleep() and usleep() functions. But they will just pause the script while it is loading.

 

Are you talking about loading a page completely, and after it loads running another PHP script/function/command later?

hello rhodesa and cooldude832;

 

this question is in conjunction with another question regarding the question: 'can php ping client-side apps';

 

by the way, 'timeout' is a mis-nomer ( javascript uses the term );

 

really a time-based interval is what I am interested in, so that I can perform a function ( ie, a ping function ) every 85 milliseconds;

 

thanks

like I said on your  other thread php can't self activate nor can it run concurrently it needs to be activated via cron or a user pointing to it

[dsdsdsdsd]

I will look into cron;

UPDATE: Ignore this...I missed the "client side app" portion...

 

right, but you could do something like:

 

<?php
  $host = "www.hostname.com";
  while(1){
    passthru("ping -n 1 $host");
    usleep(85000);
  }
?>

 

When run, it will continually ping/wait 85 milliseconds until you cancel the script

You will probably have to use AJAX to be able to activate your script every x seconds.

Your host company will probably shut u done for that, not to mention you can get cron to run every 30 minutes or faster if need be
