Request Checker Always Return True

[abilsabili50]

This is because the code below will return false if string "/charge" doesn't exists and 0 (falsy value) if exists.

!strpos($_SERVER['REQUEST_URI'], '/charge')

To fix this, you should explicitly check if strpos returns false instead of relying on the falsy nature of 0. Here's the corrected code:

if (strpos($_SERVER['REQUEST_URI'], '/charge') === false) {
  http_response_code(404); 
  echo "wrong path, make sure it's `/charge`"; 
  exit();
}
