网站建设基础-使用if和switch分别输出今天为周几

<?php
    $week=date("D");
//  echo $week;
          
    if($week=="Mon"){
        echo "星期一";
    }elseif($week=="Tue"){
        echo "星期二";
    }elseif($week=="Wed"){
        echo "星期三";
    }elseif($week=="Thu"){
        echo "星期四";
    }elseif($week=="Fri"){
        echo "星期五";
    }elseif($week=="Sat"){
        echo "星期六";
    }elseif($week=="Sun"){
        echo "星期日";
    }
      
echo "<br><hr><br>";
//使用switch输出今天是星期几
    switch($week){
        case "Mon":
            echo "星期一";
            break;
        case "Tue":
            echo "星期二";
            break;
        case "Wed":
            echo "星期三";
            break;
        case "Thu":
            echo "星期四";
            break;
        case "Fri":
            echo "星期五";
            break;
        case "Sat":
            echo "星期六";
            break;
        case "Sun":
            echo "星期日";
            break; 
    }
      
?>
