In many cases, conditions, issued on separate lines, are actually more readable, than as a single line. You can see examples in the #3392321: Relax the "Conditions should not be wrapped into multiple lines" rule for more code readability.

Option A

Conditions should not be wrapped into multiple lines if they are simple. Long conditions can be formatted by separate lines per condition, with each condition on a separate line. Example:

    if (
      $this->entity->isPublished()
      && $this->entity->is_protected_by_access_code->value == TRUE
      && $this->requestStack->getCurrentRequest()->query->get('access-code') == $accessCode
    ) {
      // Do something.
    }
