PHP-DI - Differences Between Factories and Objects

Question

PHP-DI allows some methods to define injections, including factories and objects: http://php-di.org/doc/php-definitions.html .

Plants

TestClass::class => function () {
   return new TestClass('param');
}

An instance TestClassis created lazily only when necessary.

The objects

TestClass::class => DI\object()->constructor('param')

If you use objects, is the tape also lazy to create?

If so, what is the difference between factories and facilities?

Answer 1

The PHP-DI author here seems to have some confusion (given the question and how the other answer is wrong). I improved the documentation, I hope this clarifies the situation: ec8120ee .
