Api multiple request httpful.phar Fatal error

Question

I want to get 2 different sets of data using 2 different apis and display it on the same page. The first dataset displays fine however when doing the second request i get the error:

Warning: Constant already defined in C:\xampp\htdocs\exempel\biblo\httpful.phar on line 7

Fatal error: Cannot declare class Httpful\Bootstrap, because the name is already in use in phar://C:/xampp/htdocs/exempel/biblo/httpful.phar/Httpful/Bootstrap.php on line 11

What am i doing wrong? Is it possible to send 2 requests like this or do i have to solve it some other way?

I am using the standard httpful.phar, The code used here is just example code for my real project however the problem is the same, that i cannot do 2 requests. If any more information is needed i am happy to provide it!

Thanks and have a good day!

Code bellow:
