Analysis of Methods to Get the Number of Days Between Given Dates in PHP

This article demonstrates how to obtain the number of days between two dates in PHP. Share it for reference, as follows:

Method 1:

<?php
function count_days($a,$b){
 $a_dt=getdate($a);
 $b_dt=getdate($b);
 $a_new=mktime(12,0,0,$a_dt['mon'],$a_dt['mday'],$a_dt['year']);
 $b_new=mktime(12,0,0,$b_dt['mon'],$b_dt['mday'],$b_dt['year']);
 return round(abs($a_new-$b_new)/86400);
}
//Today and2017year8month26How many days of difference
$date1=strtotime(date("Y-m-d"));
$date2=strtotime('2017-8-26);
$result=count_days($date1,2);
echo $result;
?>

Running Result:187

Method Two:

<?php
//Today and2017year8month26How many days of difference
$Date_1=date("Y-m-d");
$Date_2="2017-8-26";
$d1=strtotime($Date_1);
$d2=strtotime($Date_2);
$Days=round(($d2-$d1)/3600/24);
echo ".\$Days=round(\$d2017year8month26Day Difference ".\$Days." days;
?>

Running Result:

Today and2017year8month26Day Difference187day
