PHP Class Exercises : Calculate the difference between two dates
Calculate the difference between two dates using PHP OOP approach.
Sample Dates : 1981-11-03, 2013-09-04
Sample Salution:
PHP Code:
<?php
// Create a new DateTime object representing the start date "1981-11-03"
$sdate = new DateTime("1981-11-03");
// Create a new DateTime object representing the end date "2013-09-04"
$edate = new DateTime("2013-09-04");
// Calculate the interval between the two dates
$interval = $sdate->diff($edate);
// Output the difference between the dates in years, months, and days
echo "Difference : " . $interval->y . " years, " . $interval->m . " months, " . $interval->d . " days ";
?>
Output:
Difference : 31 years, 10 months, 1 days
Explanation:
In the exercise above,
- $sdate = new DateTime("1981-11-03");: This line creates a new DateTime object named '$sdate' representing the start date "1981-11-03".
- $edate = new DateTime("2013-09-04");: This line creates a new DateTime object named '$edate' representing the end date "2013-09-04".
- $interval = $sdate->diff($edate);: This line calculates the difference between the start date '$sdate' and the end date '$edate' using the "diff()" method, and stores the result in the variable '$interval'.
- echo "Difference : " . $interval->y . " years, " . $interval->m . " months, " . $interval->d . " days ";: This line outputs the difference between the two dates in years, months, and days by accessing the properties $interval->y (years), $interval->m (months), and $interval->d (days) of the "$interval" object.
