PHP Calculation Date Difference Days Example Analysis _php skill

In this paper, we analyze how to calculate the date difference between days in PHP. Share to everyone for your reference, specific as follows:

? PHP
//Today and October 27, 2016 difference between the number of days
$Date _1=date ("y-m-d");
$Date _2= "2016-10-27";
$d 1=strtotime ($Date _1);
$d 2=strtotime ($Date _2);
$Days =round (($d 1-$d 2)/3600/24);
Echo  "Today differs from October 27, 2016". $Days. " Days ";
echo "<br>";
How many days are there
$Date _1=date ("y-m-d") today to September 9, 2018;
$Date _2= "2018-09-09";
$d 1=strtotime ($Date _1);
$d 2=strtotime ($Date _2);
$Days =round (($d 2-$d 1)/3600/24);
Echo  "Today to September 9, 2018 there is also". $Days. " Days ";

$arrayStartDate =explode ("/", $myStartDate); 
$arrayEndDate = Explode ("/", $myEndDate);
$jdStartDate = Cal_to_jd (Cal_gregorian, $arrayStartDate [1], $arrayStartDate [0], $arrayStartDate [2]);
$jdEndDate = Cal_to_jd (Cal_gregorian, $arrayEndDate [1], $arrayEndDate [0], $arrayEndDate [2]);
$duration = $jdEndDate-$jdStartDate + 1;

Count data that expires after a few days

DateDiff (Yxdate_star,now ())

Return days: Yxdate_star-now ()
