Does the 'use' keyword trigger autoloading in PHP?

Question

In the example below, at what point does the autoloader load the class file, if at all? For example, if $boolean_test === false does the Subpackage get loaded?<

Answer 1

No use does not trigger autoloading. You can have an invalid use at the top of your file and PHP won't complain.

Autoloading happens when you attempt to use the class.
