function getDays($month, $year) 
{ 
switch($month) 
{ 
case 4: 
case 6: 
case 9: 
case 11: 
$days = 30; 
break; 
case 2: 
if ($year%4==0) 
{ 
if ($year 0==0) 
{ 
$days = $year@0==0 ? 29 : 28; 
} 
else 
{ 
$days =29; 
} 
} 
else 
{ 
$days = 28; 
} 
break; 
default: 
$days = 31; 
break; 
} 
return $days;

$week_num = date("w",$time_stamp); 
switch($week_num) 
{ 
case "0": 
$week = "日";

case '2': 
$week = "二"; 
break; 
case '3': 
$week = "三";
