: This article mainly introduces how PHP can implement a date several days later than the specified date. if you are interested in the PHP Tutorial, refer to it. This function is very simple, that is, adding a day to the specified time to get the new date. if you want to extend it, it is very easy.
Next, let's take a look at this function. First, let's talk about a function in advance to determine whether it is a leap year function.
Function CheckRun ($ year ){
If ($ year % 4 = 0 & ($ year % 100! = 0 | $ year % 400 = 0 ))
Return true;
Else
Return false;
}
We need to use this function in the following program.
Function DateAdd ($ date ){
$ Parts = explode ('', $ date );
$ Date = $ parts [0];
$ Time = $ parts [1];
$ Ymd = explode ('-', $ date );
$ Hms = explode (':', $ time );
$ Year = $ ymd [0];
$ Month = $ ymd [1];
$ Day = $ ymd [2];
$ Hour = $ hms [0];
$ Minute = $ hms [1];
$ Second = $ hms [2];
$ Day = $ day + 1; // you can add the date first.
If ($ month = '1' | $ month = '3' | $ month = '5' | $ month = '7' | $ month = '8' | $ month = '10' | $ month = '12 ')
If ($ day = 32)
{
$ Day = '1 ';
$ Month ++;
}
If ($ month = '4' | $ month = '6' | $ month = '9' | $ month = '11 ')
If ($ day = 31)
{
$ Day = '1 ';
$ Month ++;
}
If ($ month = '2 ')
If (CheckRun ($ year ))
{
// 29 days for January 1, February
If ($ day = 30)
{
$ Day = 1;
$ Month ++;
}
}
Else
{
// Not a leap year
If ($ day = 29)
{
$ Day = 1;
$ Month ++;
}
}
If ($ month = 13)
{
$ Month = 1;
$ Year ++;
}
Return $ year. "-". $ month. "-". $ day;
}
Okay. let's test it.
Echo DateAdd ("11:11:11 ");
Echo DateAdd ("11:11:11 ");
The above describes how to implement the date after several days of the specified date in PHP, including some content, hope to be helpful to friends who are interested in the PHP Tutorial.
