unexpected 'use' (T_USE) when trying to use composer

Question

So, I am trying to use the coinbase API. I'm attempting a simple test to see if I can make it work, but I'm getting various composer errors.

Currently, I am getting unexpected t 'use' for this code:

            use Coinbase\Wallet\Client;
            use Coinbase\Wallet\Configuration;

            $apiKey = 'public';
            $apiSecret = 'private';
            $configuration = Configuration::apiKey($apiKey, $apiSecret);
            $client = Client::create($configuration);
            $spotPrice = $client->getSpotPrice();
            echo $spotPrice;

So, are my use statements in the wrong place? Ive tried them outside the index function and outside the class. Both yield completely different sets of results than this.

Outside of the Keks class, I get

Fatal error: Class 'Coinbase\Wallet\Configuration' not found in /home/content/61/11420661/html/beta/application/controllers/keks.php on line 15

And inside the class but outside the index() function I get

Fatal error: Trait 'Coinbase\Wallet\Client' not found in >/home/content/61/11420661/html/beta/application/controllers/keks.php on line 4

Is there something wrong in my composer.json maybe?

Which version of php do you use? In case of doubt try <?php echo phpversion(); — VolkerK
Then please run <?php echo phpversion(); to get the version. — VolkerK
oh and by the way: The actual error message is parse error: syntax error, unexpected 'use' (T_USE) or is it something else? (If it is: what is before the code snippet you've posted?) — VolkerK
The exact message is at the end of this, the code is exactly what I've shown in the pastbin link "Parse error: syntax error, unexpected 'use' (T_USE) in /home/content/61/11420661/html/beta/application/controllers/keks.php on line 9" — Dan Smith

You cannot use "use" where you are using it.

The "use" keyword is either in front of a class definition to import other classes/interfaces/traits into it's own namespace, or it is inside the class (but not inside a method) to add traits to the class.

<?php
namespace Foo;

use Different\Class; // use can go here

class Bar {
  use TraitCode; // use can go here

  public function baz() {
    $this->traitFunction('etc');
    // use CANNOT go here
  }
}
