Want to REFRESH site every X minutes until....

[cbr_600rr]

Hi everyone, I have a block of code, or I guess an entire php page that I would like to refresh itself.  I have found several ways to refresh a page every couple of minutes, but how would I go about doing so for a given period of time.

 

either...

 

1.) Refresh page every 5 minutes for 2 hours, or..

 

2.) Refresh page every 5 minutes until 3:00PM (Central time)

 

 

Im more interested in the 2nd option, however either would be useful.

 

thanks

I know how to do basic refreshes, I am trying to figure out how I can limit it to do so for either X amount of time, or until a certain time of day.

well use date funcion or something

First 1) You could use PHP sessions to store the time of the first refresh, then run a conditional to see if it has been 2 hours yet. For 2) You could do something similar, just no sessions required, just check the time of day.

 

// 1)
session_start();
if(!isset($_SESSION['first']))
     $_SESSION['first'] = time();
if($_SESSION['first'] + 60*60*2 < time())
     // Some refresh method

// 2)
date_default_timezone_set('...whatever timezone you want this based on');
if(intval(date('G')) < 15)
     // Some refresh method

 

You might need to use sessions on the second way depending on how you want it to work.
