Im using this code to generate a random number:
The problem is, I want this to generate a new random number every hour. So basically I want it to generate a number that lasts for 1 hour, then have it generate another number, automatically.PHP Code:<?php
srand ((double) microtime( )*1000000);
$random_number = rand(1000,5000);
echo "$random_number";
?>
Is this possible, any ideas on how to do this?
Thank you in advance.
Store your random number in a cookie that has a life span of one hour. If no cookie exists, create a new random number.
Is this random number specific to one client, or to the whole site/application? More details please.
Its for the entire site. I just need to set a different number every hour.
Im now using this inside my function, its sets a cookie for one hour:
What way could I implement the cookie option as described above?PHP Code:srand(floor(time() / (60*60)));
$output = rand() % 10000;
If you use cookies, each user will see a different number. You need to store the number (and last update time) in a file or a database instead. On each page request, check if the time is greater than last update time plus one hour; if so, generate and save a new number.
You got any sample scripts of this?
