In his example, he currently returns the result of a get() call on a registry value to a variable and gets the first value (of an array) from it. His suggestion, though is to simplify it down to something like:

$one = Zend_Registery::get('myArray')[0];

Making it even easier (and more elegant) to work with returned array values.

Will Ruby kill PHP? The short answer is: no.

He takes the reader on a trip through his reasoning - things like "Ruby is elegant, but not complex" and "Java nerds love Ruby". But, one of the things that is talked most about for Ruby (everything's an object) is the same reason why PHPers and those looking for a quick, powerful, easy-to-use language will still stick with PHP.
