}
class Factory extends FactoryBase {
public function new_feature() : AppFeature { return new AppFeature; }
}
$factory = new Factory();
$feature = $factory->new_feature();
assert( is_a( $feature, 'AppFeature' ) );

The .so file (shared object) is in modules/pext.so

Configured it like this:
------------------- Sun May 23 13:44:47 root@tact:/usr/lib/php/20170718 # cat /etc/php/7.2/cli/conf.d/pext.ini extension=pext.so -------------------
And I can build it like this:
