PHP Date Exercises : Calculate number of days between two dates

Last update on December 20 2024 10:18:47 (UTC/GMT +8 hours)

Write a PHP script to calculate number of days between two dates.

Sample Solution:

PHP Code:

<?php
$to_date = time(); // Current date and time in Unix timestamp format
$from_date = strtotime("2012-01-31"); // Convert the specified date string to a Unix timestamp
$day_diff = $to_date - $from_date; // Calculate the difference in seconds between the two timestamps
echo floor($day_diff/(60*60*24))."\n"; // Convert the difference to days and print it
?>

Output:

1988

N.B.: The result may vary for your system date and time.

Explanation:

The above PHP code converts the date string '12-05-2014' into a Unix timestamp using the "strtotime()" function. The "strtotime()" function parses the given date/time string and returns the Unix timestamp representing that date/time. Finally, it prints the Unix timestamp to the standard output.
