It uses the Linux command
uptime and strips the unecessary gubbins from the output string:
This results contains some useful info including number of users logged on and loads as well as the uptime:
18:10:45 up 39 days, 22:04, 1 user, load average: 0.07, 0.06, 0.08
All you have to do is to insert the following php code into your page and you are away.
<?php $data = shell_exec('uptime'); $first = strpos($data, 'up'); $data = substr($data,$first); $first = strpos($data, ','); $data = substr($data,0,$first); $data = str_replace('up','Powered by Raspberry Pi, ',$data); echo $data . ' uptime' ?>
You can see the results from my site at the footer of the page.
Powered by Raspberry Pi, 39 days uptime
