Generating invalid PHP code

[bkuhl]

I'm running into the following issue when trying to get the contents for https://survivetheark.com/index.php?/forums/forum/5-changelog-patch-notes/.

   Symfony\Component\Debug\Exception\FatalThrowableError  : Parse error: syntax error, unexpected ')'

  at /Users/bkuhl/Personal/myproject/vendor/tunaabutbul/cloudflare-middleware/src/CloudflareMiddleware.php: 205
  202:             /*
  203:              * Eval PHP and get solution
  204:              */
  205:             eval($php_code);
  206:             // Split url into components.
  207:             $uri = parse_url($request->getUri());
  208:             // Add host length to get final answer.
  209:             $params['jschl_answer'] += strlen($uri['host']);

The PHP output it's generating is:

$params['jschl_answer']=);$params['jschl_answer']=+(((!0)+!(!1)+!(!1)+!(!1)+!(!1)+!(!1)+!(!1)+!(!1)+(0)).(+!(!1)).((!0)+!(!1)+!(!1)+!(!1)+!(!1)+!(!1)+!(!1)).((!0)+!(!1)+!(!1)+!(!1)+!(!1)).(+(0)).((!0)+!(!1)+!(!1)+!(!1)).((!0)+!(!1)).((!0)+!(!1)+!(!1)+!(!1)+!(!1)).((!0)+!(!1)+!(!1)));$params['jschl_answer']*=+(((!0)+!(!1)+!(!1)+!(!1)+!(!1)+!(!1)+!(!1)+!(!1)+(0)).(+!(!1)).((!0)+!(!1)+!(!1)+!(!1)+!(!1)+!(!1)+!(!1)).((!0)+!(!1)+!(!1)+!(!1)+!(!1)).(+(0)).((!0)+!(!1)+!(!1)+!(!1)).((!0)+!(!1)).((!0)+!(!1)+!(!1)+!(!1)).((!0)+!(!1)+!(!1)));
