PHP displays time as 'just', 'n minutes/hours ago', etc.

In many occasions, in order to show the timeliness of information, the time is usually displayed as "just now", "5 minutes ago", "3 hours ago", etc. instead of printing the time directly. For example, Weibo and SNS applications have long used this function. The time format generally stored in the database is Unix timestamp, so here is a PHP function that converts Unix timestamp into timeline display.

date_default_timezone_set('PRC');
$date = "1351836000";
echo tranTime($date);

function transfer_time($time)
{
 $rtime = date(" m-d H:i",$time);
 $htime = date("H:i",$time);

 $time = time() - $time;

 if ($time < 60)
 {
 $str = 'just';
 }
 elseif ($time < 60 * 60)
 {
 $min = floor($time/60);
 $str = $min.'minutes ago';
 }
 elseif ($time < 60 * 60 * 24)
 {
 $h = floor($time/(60*60));
 $str = $h.'hours ago'.$htime;
 }
 elseif ( $time < 60 * 60 * 24 * 3)
 {
 $d = floor($time/(60*60*24));
 if($d==1)
 $str = 'yesterday'.$ rtime;
 else
 $str = 'the day before yesterday'.$rtime;
 }
 else
 {
 $str = $rtime;
 }
 return $str;
}

?>
