  "; $ Col = 0; // Print the table header ///?>
 
  "; $ U2 ="

  ". $ Weekvalue .""; Echo" 
   "; //// Print the date list ///// when the month is, a value is deleted from the end of the array, that is, 31 is deleted. if ($ Month = 4 or $ Month = 6 or $ Month = 9 or $ Month = 11) {array_pop ($ Maxday); $ Maxday_count --;} // first judge whether the month is February. If yes, then judge whether the year is a leap year. if yes, remove two values from the end of the array; otherwise, remove three values. if ($ Month = 2) {if ($ Year % 4 = 0) {array_pop ($ Maxday); $ Maxday_count-= 2 ;} else {array_pop ($ Maxday); $ Maxday_count-= 3 ;}} //// print the date //// while ($ daynum <$ Maxday_count) {echo"
