Showcase: The create() function

at 2007-05-06 in Examples by friebe (0 comments)

As a side product of RFC #0106, the create() core functionality, which is used to create generic objects, provides an overloaded variant of itself: When passed an object, it will return it.

This may seem a bit strange (and kind of useless) in the first moment, but actually solves a deficit in the PHP parser, which does not allow chaining after new:

<?php 
  $c= new Criteria()->add('author_id', 501, EQUAL);  // Parse error
?>

By using create(), we can work around this as follows:

<?php 
  $c= create(new Criteria())->add('author_id', 501, EQUAL);
?>
