If PHPExcel doesn't use namespaces, then it lives in the root namespace \.
You just use it like you would any old non-namespaced code.
I think the confusion comes from the PHP manual interchanging aliasing
and importing. The use statement only creates an alias. It does not do
any importing per se, but rather creates a named link to another
namespace, class or interface.
So that said, you can still use the "use" statement to "import" the
PHPExcel_IOFactory into your current scope:
namespace MyApp;
use \PHPExcel_IOFactory as ExcelFactory; <- alias is created
new ExcelFactory (); // \PHPExcel_IOFactory <- autoloading happens here
As a further example:
namespace MyApp {
class PHPExcel {} // \MyApp\PHPExcel
}
class PHPExcel {} // \PHPExcel
-- then somewhere else ---
namespace MyApp{
new PHPExcel; // \MyApp\PHPExcel is loaded (first class defined above)
new \PHPExcel; // \PHPExcel (second class defined above)
}
namespace MyApp{
use \PHPExcel;
// must use leading \ otherwise it will alias the one in the MyApp namespace
new PHPExcel; // \PHPExcel;
new \MyApp\PHPExcel; // \MyApp\PHPExcel
}
Cheers,

Thanks for the reply, Marco.
While I haven't been that fortunate to deal with a lot of modern code that uses
namesapces, I'm familiar with the
concepts. I re-read the manual before posting just in case I was missing
something simple and I didn't think that I was.
Here's my understanding, please correct me if I'm wrong:
The static method createReaderForFile() is in the class PHPExcel_IOFactory,
which lives within the PHPExcel directory.
Since the library doesn't use namespaces, underscores denote a subdirectory -
just like in ZF1.
Give the fact that the PHPExcel class lives in
/vendor/phpoffice/phpexcel/Classes and the autoload_namespaces.php maps
'PHPExcel' to that directory, I would expect that by adding the 'use' statement
in another file would permit access to
the method without any namespace prefixes or separators. I can see that if I
omitted the use, then without the leading
'\', PHP would think that I'm referring to a class that's in the current
namespace, but that's not the case.
Everything I've ready seems to back up that theory, but since it's not working
as expected, I'm still missing something.

P.S. That 2 min video is great - I'll have to pass it on to colleagues who are
namespace-ignorant.

Correct. That's basic PHP namespaces knowledge though.
Here's a couple of resources you should read up before dealing with namespaces:
The manual (obviously): http://php.net/manual/en/language.namespaces.php
