[Robert Stoll] Same applies here, my use statement is outside of a namespace Adam's isn't. > For that matter, what about this: > > use GuzzleHttp\Client; > > include __DIR__.'/vendor/autoload.php'; > > $client = new Client; > // $client is a GuzzleHttp\Client object > > namespace Foo; > $client = new Client; > // $client is a Foo\Client object > > Certainly this code is not *sensible*, but it does have a meaningful behaviour, which derives > directly from the previous > examples and documented uses of the namespace keyword.

If I rewrite your code to the following: namespace{ use GuzzleHttp\Client; include __DIR__.'/vendor/autoload.php'; $client = new Client; // $client is a GuzzleHttp\Client object namespace Foo{ $client = new Client; // $client is a Foo\Client object } Then it would make sense (use statement is inside a namespace).
