php返回相對時間，如：20分鐘前，3天前

function plural($num) { if ($num != 1) return "s"; } function getRelativeTime($date) { $diff = time() - strtotime($date); if ($diff<60) return $diff . " second" . plural($diff) . " ago"; $diff = round($diff/60); if ($diff<60) return $diff . " minute" . plural($diff) . " ago"; $diff = round($diff/60); if ($diff<24) return $diff . " hour" . plural($diff) . " ago"; $diff = round($diff/24); if ($diff<7) return $diff . " day" . plural($diff) . " ago"; $diff = round($diff/7); if ($diff<4) return $diff . " week" . plural($diff) . " ago"; return "on " . date("F j, Y", strtotime($date)); } 複製代碼
