4Depends if you're running a 32-bit or 64-bit version of PHP – Mark Baker Apr 28 '11 at 23:29

Of course, when the time comes PHP 42.1.3 will natively support 64-bit integers.

php version 42? PHP born about 10 years ago and now it's version 5 :) i don't think in 20 years it will reach version 42 – dynamic Apr 28 '11 at 23:38

@yes123 Whatever version we have by then, I do know that PHP6 will still be on the horizon somewhere. – Wiseguy Apr 28 '11 at 23:41

Yes, it should be. But let me run that code in my VirtuaBox and changed the date as well in there.
you know it could be fun to try it out :)

1You'll probably get a signed (negative) integer. Let me know how it goes! ;) – Alix Axel Apr 28 '11 at 23:31

also I'm imagining that by that time, there will be a better language, new language or it might not be even called PHP anymore – fedmich Apr 28 '11 at 23:32

@fedmich: No, RoR will be gone and PHP will still rule the world! NURV! :P – Alix Axel Apr 28 '11 at 23:34

@fedmich If PHP's name changes, it'll probably change to "PHP", where the first P stands for "PHP", [of which the first P stands for "PHP"](http://en.wikipedia.org/wiki/Recursive_acronym). Infinite recursion will crash the Internet. – Wiseguy Apr 28 '11 at 23:37

Wait a moment. I Don't think you have to run a virtualbox to change the date in your os – dynamic Apr 28 '11 at 23:43

4I just execute it and I got -2138856280 ... looks like our apps will break then :( – fedmich Apr 28 '11 at 23:48

@yes123 I couldnt change the date of my computer/server as there's too many apps going on and processing some stuff; so I could only execute codes like this via virtuabox. – fedmich Apr 28 '11 at 23:50

You can fake the system time using [libfaketime](http://www.code-wizards.com/projects/libfaketime/index.html). On Linux x86_64 with PHP 5.4.13, the value returned is not negative. `LD_PRELOAD=src/libfaketime.so.1 FAKETIME="31337-12-12 00:00:00" php -r 'echo time(),"\n";'` gives `48541007779`. Oh, but `date` seems to have issues interpreting `31337` though (`3508-03-16`). On the lucky side, `4242` works! – Lekensteyn Mar 23 '13 at 22:05
