YouTube style "x minutes ago"

[alej469]

 

Just a quick one: I'm a complete novice with unix timestamps. How could I display the time a user registered in minutes (from a unix timestamp) for users that registered less than an hour ago? I'm basically hoping to do a YouTube style thing like you get on the comments, which displays the number of seconds ago the comment was made if it was under a minute ago, the number of minutes it was made if it was under a hour ago etc... Is this going to be complicated? Cheers for any help!

obviousally this will always return 0 minutes... but its only sleeping for 10 seconds...just pull time1 from the database...

<?
$time1=time();
sleep(10);
$time2=time();

$dif=$time2-$time1;
$min=0;
while($div>=0){
$min++;
$dif-=60;
}
echo "$min minutes ago"
?>
