这段代码判断当前日期是星期几,根据返回值输出Today is Monday的字样,使用switch语句记得每个case后面跟着一个break语句
<html> <body> <?php $d=date("D"); switch ($d) { case "Mon": echo "Today is Monday"; break; case "Tue": echo "Today is Tuesday"; break; case "Wed": echo "Today is Wednesday"; break; case "Thu": echo "Today is Thursday"; break; case "Fri": echo "Today is Friday"; break; case "Sat": echo "Today is Saturday"; break; case "Sun": echo "Today is Sunday"; break; default: echo "Wonder which day is this ?"; } ?> </body> </html>
