[SGVLUG] timediff - c++ version - command line program

[Sean O'Donnell]

Nice!

In PHP (not sure about python or perl on this method), you can use the
DateTime object.

Example:

#!/usr/bin/env php
<?php
$d1 = new DateTime('2000-01-01');
$d2 = new DateTime('2016-09-09');
print $d1->diff($d2)->days;
?>

It's also nice for revealing other information about the date difference.

Example:

print_r($d1->diff($d2)->days);


Outputs:

DateInterval Object
(
    [y] => 16
    [m] => 8
    [d] => 8
    [h] => 0
    [i] => 0
    [s] => 0
    [invert] => 0
    [days] => 6096
)


Just thought to mention in case it was useful for some (other) poor
unfortunate php geek.
