[RESOLVED] Ternary difference in version?

[Derokorian]

Hi guys!

I have this line which works perfectly fine on my laptop, and at work running php 5.3.4 and 5.3.8 respectively:

      $userTopScore = isset($_SESSION['userid']) ? $this->Model->getUserTopScores($_SESSION['userid']) ?:NULL : NULL;

However on my hosted server (publicly viewable domain) which is running 5.2.17 I get the following error:

Parse error: syntax error, unexpected ':' in /path/to/controllers/JumbleWords.php on line 40

However I can't seem to find any mention of it in the changelog other than:

Fixed bug #49269 (Ternary operator fails on Iterator object when used inside foreach declaration). (Etienne, Dmitry)

However this line is in both the version changes for 5.2.11 and 5.3.1 tho the Iterator object doesn't seem to be involved. Any ideas why I can't use ternary this way on the older version? Is there a setting somewhere that I have on my two controlled machines but not on the server?

Damn it never mind, its not in the change log but I found it in the Operators section of the manual:

Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise.
