这里给定一个时间，计算这个时间在多久前，比如：2天前，1年前
function prettyDate($date){ ???????$time = strtotime($date); ???????$now = time(); ???????$ago = $now - $time; ???????if($ago < 60){ ???????????$when = round($ago); ???????????$s = ($when == 1)?"second":"seconds"; ???????????return "$when $s ago"; ???????}elseif($ago < 3600){ ???????????$when = round($ago / 60); ???????????$m = ($when == 1)?"minute":"minutes"; ???????????return "$when $m ago"; ???????}elseif($ago >= 3600 && $ago < 86400){ ???????????$when = round($ago / 60 / 60); ???????????$h = ($when == 1)?"hour":"hours"; ???????????return "$when $h ago"; ???????}elseif($ago >= 86400 && $ago < 2629743.83){ ???????????$when = round($ago / 60 / 60 / 24); ???????????$d = ($when == 1)?"day":"days"; ???????????return "$when $d ago"; ???????}elseif($ago >= 2629743.83 && $ago < 31556926){ ???????????$when = round($ago / 60 / 60 / 24 / 30.4375); ???????????$m = ($when == 1)?"month":"months"; ???????????return "$when $m ago"; ???????}else{ ???????????$when = round($ago / 60 / 60 / 24 / 365); ???????????$y = ($when == 1)?"year":"years"; ???????????return "$when $y ago"; ???????} ???}
使用：
echo prettyDate("2012-07-22 12:23:45")php计算给定时间之前的函数
