PHP outputs the time difference function
<?php
date_default_timezone_set('PRC'); // The default time zone
echo " Today, :",date("Y-m-d",time()),"<br>";
echo " Today, :",date("Y-m-d",strtotime("18 june 2008")),"<br>";
echo " Yesterday, :",date("Y-m-d",strtotime("-1 day")), "<br>";
echo " Tomorrow, :",date("Y-m-d",strtotime("+1 day")), "<br>";
echo "1 Weeks later, :",date("Y-m-d",strtotime("+1 week")), "<br>";
echo "1 Weeks and two days 4 In two hours :",date("Y-m-d G:H:s",strtotime("+1 week 2 days 4 hours 2 seconds")), "<br>";
echo " Next week, 4:",date("Y-m-d",strtotime("next Thursday")), "<br>";
echo " Last week, 1:".date("Y-m-d",strtotime("last Monday"))."<br>";
echo "1 Months ago, :".date("Y-m-d",strtotime("last month"))."<br>";
echo "1 After one month :".date("Y-m-d",strtotime("+1 month"))."<br>";
echo "10 Years later, :".date("Y-m-d",strtotime("+10 year"))."<br>";
?>
When I was studying PHP, I often used to get the date of a period of time before or after the present. Now that you've collected it, you can also expand it
// Get the day of the week ( 1-7 )
function GetWeek($times)
{
$res = date('w', strtotime($times));
if($res==0)
$res=7;
return $res;
}
// Get the time of day
function GetTime($times)
{
$res = date('H:i', strtotime($times));
return $res;
}
// Get a few months now
function GetMonth($Month,$type='l')
{
if(!strcmp($type,'b'))
$res=date("Y-m-d H:i:s",strtotime("-$Month months"));
if(!strcmp($type,'l'))
$res=date("Y-m-d H:i:s",strtotime("+$Month months"));
return $res;
}
// Get the current time
function GetCurrentDateTime()
{
$res=date("Y-m-d H:i:s",time());
return $res;
}
// Gets the time before or after the current time several hours apart
function GetDiffHours($hours,$type='l')
{
if(!strcmp($type,'b'))
$res=date("Y-m-d H:i:s",strtotime("-$hours hour"));
if(!strcmp($type,'l'))
$res=date("Y-m-d H:i:s",strtotime("+$hours hour"));
return $res;
}
// A few minutes before or after
function GetDiffMinute($Minute,$type='l')
{
if(!strcmp($type,'b'))
$res=date("Y-m-d H:i:s",strtotime("-$Minute minute"));
if(!strcmp($type,'l'))
$res=date("Y-m-d H:i:s",strtotime("+$Minute minute"));
return $res;
}
// A few seconds before or after
function GetDiffSec($sec,$type='l')
{
if(!strcmp($type,'b'))
$res=date("Y-m-d H:i:s",strtotime("-$sec second"));
if(!strcmp($type,'l'))
$res=date("Y-m-d H:i:s",strtotime("+$sec second"));
return $res;
}
// A few weeks before or after
function GetDiffWeek($Week,$type='l')
{
if(!strcmp($type,'b'))
$res=date("Y-m-d H:i:s",strtotime("-$Week week"));
if(!strcmp($type,'l'))
$res=date("Y-m-d H:i:s",strtotime("+$Week week"));
return $res;
}
// A period of time between days
function GetDiffDays($days,$type='l')
{
if(!strcmp($type,'b'))
$res=date("Y-m-d H:i:s",strtotime("-$days day"));
if(!strcmp($type,'l'))
$res=date("Y-m-d H:i:s",strtotime("+$days day"));
return $res;
}
// Years before or after
function GetDiffYears($year,$type='l')
{
if(!strcmp($type,'b'))
$res=date("Y-m-d H:i:s",strtotime("-$year year"));
if(!strcmp($type,'l'))
$res=date("Y-m-d H:i:s",strtotime("+$year year"));
return $res;
}
