PHP calculates the day of the week for a certain day in a time period, the number of days after the current time and the date and time difference_PHP Tutorial

These time functions have been released. Needless to say how to use them! If there is anything you don’t understand, you can leave a message below and I will reply in time. Make a friend~

The code is as follows

代码如下

复制代码

//取两个日期内天数差 function SubDay($ntime,$ctime) { $dayst = 3600 * 24; $cday = ceil(($ntime-$ctime)/$dayst); return $cday; } //取当前时间后几天，天数增加单位为1 function AddDay($ntime,$aday) { $dayst = 3600 * 24; $oktime = $ntime + ($aday * $dayst); return $oktime; } //取一周内的某天是星期几 function AddSpeDay($day=0) { //$day = isset($day) ? intval($day) : 0; $daynum = date(‘w’) – $day; $oktime = time() – (3600 * 24 * $daynum); return $oktime; } #附php取当前时间的方法 //取当前时间，格式为2009-10-23 14:20:35 function GetDateTimeMk($mktime) { return MyDate(‘Y-m-d H:i:s’,$mktime); } //取当前时间，格式为2009-10-23 function GetDateMk($mktime) { return MyDate(“Y-m-d”,$mktime); } ?>

Copy code

//Get the difference in days between two dates
function SubDay($ntime,$ctime)
{
$dayst = 3600 * 24;
$cday = ceil(($ntime-$ctime)/$dayst);
return $cday;
}
//Get the number of days after the current time, and the increment unit of the number of days is 1
function AddDay($ntime,$aday)
{
$dayst = 3600 * 24;
$oktime = $ntime + ($aday * $dayst);
return $oktime;
}
//Get the day of the week that a certain day of the week is

function AddSpeDay($day=0)
{
//$day = isset($day) ? intval($day) : 0;
$daynum = date(‘w’) – $day;
$oktime = time() – (3600 * 24 * $daynum);
return $oktime;
}

#Attached is a method to get the current time in php //Get the current time, the format is 2009-10-23 14:20:35 function GetDateTimeMk($mktime)
{
return MyDate(‘Y-m-d H:i:s’,$mktime);
} //Get the current time, the format is 2009-10-23 function GetDateMk($mktime)
{
return MyDate(“Y-m-d”,$mktime);
} ?>
