Strtotime() Question

[tqla]

Hello. I do not need to know how to write this another way. I just am curious as to why this happens.

 

Why does strtotime() print the expected result when I add 25 years:

 

<?php
$thedate = date('D M Y', strtotime("+25 year"));
echo $thedate;
?>

 

But it fails to print the expected result when I add 26 years. Instead it reads "Wed Dec 1969"

 

<?php
$thedate = date('D M Y', strtotime("+26 year"));
echo $thedate;
?>

 

Is it my version of PHP? Is there a 25 year limit? Does this happen on your system?

 

 

Thanks.

I'm not sure as to what your problem could be as this works on my site. Perhaps a version of php problem.

On 32bit versions of php, the maximum integer value corresponds to - Tue, 19 Jan 2038 03:14:07 UTC

Thank you all.

 

SocialCloud, I'm glad it works in your (most likely later) version of PHP. Troubling that that sytax fails in some versions.

 

PFMaBiSmAd and requinix, thank you for the 2038 info, the 32bit limitation it is indeed concerning.

The php datetime class/extension should not have this problem, even on 32bit systems, assuming that you don't try to convert the result to a Unix timestamp in an integer variable.
