Php simple calendar program code

PHP provides the date () function, which provides a variety of date processing functions. There are two types of data to be obtained: the first is the total number of days of the month, and the second is the number of days of the week in which the first day of the month is located. The number indicates 0 (indicating Sunday) to 6 (Saturday ).

The date () function can easily obtain the above data.

The Code is as follows:

Copy code

<? Php $ Month = $ _ GET ['M']? $ _ GET ['M']: date ('n '); $ Year = $ _ GET ['y']? $ _ GET ['y']: date ('y '); $ Start_week = date ('w', mktime (0, 0, 0, $ month, 1, $ year )); $ Day_num = date ('T', mktime (0, 0, 0, $ month, 1, $ year )); $ End = false; ?> <Table> <Tr> <Td> Sunday </td> <td> Monday </td> <td> Tuesday </td> <td> Wednesday </td> <td> Thursday </td> <td> Friday </td> <td> Saturday </td> </Tr> <Tr> <? Php For ($ I = 0; $ I <$ start_week; $ I ++) { Echo "<td> </td> "; } $ J = 1; While ($ j <= $ day_num) { Echo "<td> $ j </td> "; $ Week = ($ start_week + $ J-1) % 7; If ($ week = 6 ){ Echo "nt </tr> n "; If ($ j! = $ Day_num) Echo "t <tr> ntt "; Else $ end = true; } $ J ++; } While ($ week % 7! = 6) { Echo "<td> </td> "; $ Week ++; } If (! $ End) Echo "n </tr> "; ?> </Table>

Advanced Class

The Code is as follows:

Copy code

<? Php Class Calendar { Private $ year; Private $ month; Private $ weeks = array ('day', 'yi', '2', '3', '4', '5', '6 '); Function _ construct ($ options = array ()){ $ This-> year = date ('y '); $ This-> month = date ('M '); $ Vars = get_class_vars (get_class ($ this )); Foreach ($ options as $ key => $ value ){ If (array_key_exists ($ key, $ vars )){ $ This-> $ key = $ value; } } } Function display () { Echo '<table class = "calendar"> '; $ This-> showChangeDate (); $ This-> showWeeks (); $ This-> showDays ($ this-> year, $ this-> month ); Echo '</table> '; } Private function showWeeks () { Echo '<tr> '; Foreach ($ this-> weeks as $ title) { Echo '<th>'. $ title.

'</td> '; } Else { Echo '<td>'. $ j. '</td> '; } If ($ I % 7 = 0 ){ Echo '</tr> <tr> '; } } Echo '</tr> '; } Private function showChangeDate () { $ Url = basename ($ _ SERVER ['php _ SELF ']); Echo '<tr> '; Echo '<td> <a href = "?
