Weird issue with evaluating numbers

Copy linkTweet thisAlerts:
Aug 14.2010

I have tried this code on two separate shared hosts and I am having the same problem.

[CODE]<?

if (06 < 07) echo ‘true’; else echo ‘false’;

if (07 < 08) echo ‘true’; else echo ‘false’;

?>
[/CODE]

The first line returns true but the second returns false. How does that make sense? This only happens if the second value is 08 or 09.

Update – Solved it by putting quotes around the numbers, but still confused on why it does not work properly without them?

@NogDogAug 14.2010 — When not quoted as a string, an integer with a leading 0 is treated as an octal number. Any invalid digit (e.g. 8 or 9) will be ignored, as will any subsequent digits. So 08 (not quoted) becomes an integer 0.
