Simple and practical PHP calendar code-PHP source code

We generally use some js plug-ins to implement the calendar program code, but we will use php programs for log classification like blogs. Let's take a look at the following tutorials for a little introduction.

The PHP calendar program features popular functions. You can pull down and switch the year from the previous year to the next year to the last year to the next year. This is too much easier to scale out, why is the title exquisite? It is because you feel that the interface is still good. Haha, let everyone laugh. Please also point out the shortcomings.

The result code is as follows:

Php calendar core code

The Code is as follows:

// Calendar Class calendar { // Current year Private $ year; // Current month Private $ month; // The first day of a month is the day of the week Private $ start_weekday; // Number of days in the current month Private $ days; // Maximum and minimum number of years, maximum and minimum number of months Private $ yearMonth = array (2080,190 0, 12, 1 ); // Constructor Function _ construct (){ If (isset ($ _ GET ['Year']) { $ This-> year = $ _ GET ['Year']; } If (isset ($ _ GET ['month']) { $ This-> month = $ _ GET ['month']; } $ This-> pnYm ($ this-> year, $ this-> month ); $ This-> days = date ('T', mktime (0, 0, 0, $ this-> month, 1, $ this-> year )); $ This-> start_weekday = date ('w', mktime (0, 0, 0, $ this-> month, 1, $ this-> year )); $ This-> style (); } // Output Private function style (){ Echo' ';$ This-> weeklist ();$ This-> daylist ();Echo' Echo' ';}// Date and month Parameter DeterminationPrivate function ymCheck ($ year, $ month ){If (!
