        Why is this an issue?

        A catch clause that only rethrows the caught exception has the same effect as omitting the catch altogether and letting it bubble up automatically.

        $s = "";
        try {
          $s = readMyFile($fileName);
        } catch (Exception $e)  {
          throw $e;  // Noncompliant
        }
        

        Such clauses should either be removed or populated with the appropriate logic.

        $s = readMyFile($fileName);
        

        or

        $s = "";
        try {
          $s = readMyFile($fileName);
        } catch (Exception $e) {
          error_log($e->getMessage());
          throw new MyException("an exception occurred", 2, $e);
        }
