How to compare two dates in php

Question

How to compare two dates in php if dates are in format \'03_01_12\' and \'31_12_11\' .

I am using this code:

$date1=date(\'         


        

Answer 1

The date_diff() function returns the difference between two DateTime objects.

If the first date is before the second date a positive number of days will be returned; otherwise a negative number of days:

format("%R%a days");
?>

output will be "+272 days" ;

changing $date1 = "2014-03-15"

 format("%R%a days");
    ?>

Output will be "-93 days"
