時間を日前、時間などの形式に変換します

時間は、「1天前」、「2月前」などのような形式に変換されます。

 function prettyDate($date){
 $time = strtotime($date);
 $now = time();
 $ago = $now - $time;
 if($ago < 60){
 $when =round($ago);
 $s = ($ when == 1)?"second":"秒";
 return "$when $s ago";
 }elseif($ago < 3600){
 $when =round($ago / 60);
 $m = ($when == 1)?"分":"分";
 return "$when $m ago";
 }elseif($ago >= 3600 && $ago  $when =round ($ago / 60 / 60);
 $h = ($when == 1)?"hour":"hours";
 return "$when $h ago";
 }elseif($ago >= 86400 && $ago  $when =round($ago / 60 / 60 / 24);
 $d = ($when == 1)?"day":"days";
 return "$when $d ago";
 }elseif($ago >= 2629743.83 && $ago  $when =round($ago / 60 / 60 / 24 / 30.4375);
 $m = ($when == 1) ?"month":"months";
 return "$m 前 $when";
 }else{
 $when =round($ago / 60 / 60 / 24 / 365);
 $y = ($when == 1)?"year":"year";
 return "$when $y ago";
 }
}

echo prettyDate("2012-07-22 12:23:45")."
echo prettyDate("2010-11-12 22:25:45")."";
echo prettyDate("2012-01-01 01:00:00")."< ;br />";
echo prettyDate("2001-05-30 00:00:00")."";
