Shorthanded if statement

While practicing for a ZEND exam, we run into the next question:

Outcome of this code:

$var =  true ? 'while' : true ? 'till' : 'false';

The answer is 'till'... But if you run it like this:

$var =  true ? 'while' : (true ? 'till' : 'false');

The outcome is 'while' as expected.

I don't understand why the first line returns 'till'. Can anyone help me? Thanks in advance!

The parentheses give it away. Without them, it runs as `$var = (true ? 'while' : true) ? 'till' : 'false';`. `'while'` is truthy so result is `'till'`. – Niet the Dark Absol Jan 19 '15 at 14:10
Thanks for explaining it. Makes it all clear! – sanderbee Jan 19 '15 at 14:22
