TalkPHP - View Single Post - Using ISSET()...How does this line of code work?

Dave · 06-11-2008, 09:43 PM

I got the code below from PHP: Hypertext Preprocessor, under the ISSET() topic. It was a "contribution" to the subject from a reader, and it did not have any accompanying comments.

It looks interesting, but can anyone explain to a person with little experience (such as I) how it works?

PHP Code:


			
$var = (isset($var) && $var) ? $var : 'new value';

Thanks,
Dave
