I finally found a use for mixed string/int keys. I have a routine that plucks key/value pairs out of one associative array and builds another, and allows you to rename the resulting key names at the same time. Using mixed keys allows you to be more terse if you don't want to change the name: $json = $data->valuesForKeyPaths(array( 'foo' => 'path.to.foo', 'bar', 'baz' => 'path.to.baz', ));
