A simple php Calender (calendar) solves the 2038 problem, which can be used on both 32-bit and 64-bit machines. The code is very simple and easy to modify.

Note that the 32-bit server has 2038 problems, so the 32-bit server's validity period ranges from ~ 2038

We can also use DateTime to avoid this problem (this is irrelevant to 32-bit 64-bit)

The Code is as follows:

<? Php

/**

* My Calendar

* Date_default_timezone_set date mktime

* @ Param int $ year

* @ Param int $ month

* @ Param string $ timezone

* @ Author fc_lamp

* @ Blog: fc-lamp.blog.163.com

Function myCalender ($ year = '', $ month ='', $ timezone = 'Asia/Shanghai ')

{

Date_default_timezone_set ($ timezone );

$ Year = abs (intval ($ year ));

$ Month = abs (intval ($ month ));

// Whether it is a 32-bit Server

If (is32 ())

{

If ($ year <1970 or $ year> = 2038)

{

$ Year = date ('y ');

}

} Else

{

If ($ year <= 0)

{

$ Year = date ('y ');

}

If ($ month <= 0 or $ month> 12)

{

$ Month = date ('M ');

}

// Previous year

$ PretYear = $ year-1;

// Last month

$ MpYear = $ year;

$ PreMonth = $ month-1;

If ($ preMonth <= 0)

{

$ PreMonth = 1;

$ MpYear = $ pretYear;

}

// Next year

$ NextYear = $ year + 1;

// Next month

$ MnYear = $ year;

$ NextMonth = $ month + 1;

If ($ nextMonth> 12)

{

$ NextMonth = 1;

$ MnYear = $ nextYear;

}

Use the DateTime class to solve the 2038 problem. The Code is as follows:
