PHP输出时间差函数代码

PHP输出时间差函数

代码如下:

PHP
date_default_timezone_set('PRC'); //默认时区
echo "今天:",date("Y-m-d",time()),"
";
echo "今天:",strtotime("18 june 2008")),"
";
echo "昨天:",strtotime("-1 day")),"
";
echo "明天:",strtotime("+1 day")),"
";
echo "一周后:",strtotime("+1 week")),"
";
echo "一周零两天四小时两秒后:",date("Y-m-d G:H:s",strtotime("+1 week 2 days 4 hours 2 seconds")),"
";
echo "下个星期四:",strtotime("next Thursday")),"
";
echo "上个周一:".date("Y-m-d",strtotime("last Monday"))."
";
echo "一个月前:".date("Y-m-d",strtotime("last month"))."
";
echo "一个月后:".date("Y-m-d",strtotime("+1 month"))."
";
echo "十年后:".date("Y-m-d",strtotime("+10 year"))."
";
?>

在学习PHP 的时候，经常会用到获取现在之前或之后，某个时间段的日期。现在已经进行收集，大家同时也可以进行扩展丰富

代码如下:

//获取当天的星期（1-7）
function GetWeek($times)
{
$res = date('w',strtotime($times));
if($res==0)
$res=7;
return $res;
}
//获取当天时间
function GetTime($times)
{
$res = date('H:i',strtotime($times));
return $res;
}
//获取现在过几月的的时间
function GetMonth($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;
}
//获取当前时间
function GetCurrentDateTime()
{
$res=date("Y-m-d H:i:s",time());
return $res;
}
//获取当前时间隔几小时之前或之后的时间
function GetDiffHours($hours,strtotime("-$hours hour"));
if(!strcmp($type,strtotime("+$hours hour"));
return $res;
}
//间隔几分钟之前或之后的时间
function GetDiffMinute($Minute,strtotime("-$Minute minute"));
if(!strcmp($type,strtotime("+$Minute minute"));
return $res;
}
//间隔几秒之前或之后的时间
function GetDiffSec($sec,strtotime("-$sec second"));
if(!strcmp($type,strtotime("+$sec second"));
return $res;
}

//间隔几个星期之前或之后的时间
function GetDiffWeek($Week,strtotime("-$Week week"));
if(!strcmp($type,strtotime("+$Week week"));
return $res;
}
// 间隔几天之间的时间
function GetDiffDays($days,strtotime("-$days day"));
if(!strcmp($type,strtotime("+$days day"));
return $res;
}
//间隔几年之前或之后的时间
function GetDiffYears($year,strtotime("-$year year"));
if(!strcmp($type,strtotime("+$year year"));
return $res;
}
