PHP shorthand syntax

Question

I\'ve just came across this on GitHub.

 ($config === NULL) and $config = Kohana::config(\'email\');

Is that the equivalent of

Answer 1

AND is a PHP logical operator.

($config === NULL) and $config = Kohana::config('email');

has equivalent outcome (but has a lesser operator precedence) to

($config === NULL) && $config = Kohana::config('email');

Personally, to avoid any confusion I would use your second approach.
