Answer
Solution:
I understand you want to include file a.php in b.php and be able to use the function in a.php.
In PHP, you can include files using require_once, require, include and include_once statements which you should have probably known about before asking this question.
To suggest a solution while you read from the links I have provided, you can use any of the above functions to include your file a.php, call the function and save the return value in a variable and print it out:
b.php
require("a.php");
$response = CheckExists("a-sample-file.txt");
print($response);
