// Please mail me if you use it and/or have any comments.
// I might add some month, and week checking too.

// Oh, and this is basically just uptime.c ported to php, i just added floor() and $ to the code. :)
// And some formatting stuff
//
// put something like this in your code:
// <?PHP echo uptime("Server up for %days days, %hours hours, %mins minutes and %secs days"); ?>
// or
// <?=time("Server up for %days days, %hours hours, %mins minutes and %secs days")?>
//
// You can also check if days is set, just use this:
// <?PHP
// if(uptime("%days") == "") {
// echo(uptime("Up for only %hours");
// } elseif(uptime("%days") > 30) {
// echo(uptime("Up for %days days!! wohoo!");
// } else {
// echo(uptime("Up for %days.");
// }
