It seems like you are loosely comparing $segment of type array|null|string against null; this is ambiguous if the string can be empty. Consider using a strict comparison !== instead.

Bug introduced by
It seems like you code against a specific sub-type and not the parent class Fhp\Message\AbstractMessage as the method getEncryptedSegments() does only exist in the following sub-classes of Fhp\Message\AbstractMessage: Fhp\Message\Message. Maybe you want to instanceof check for one of these explicitly?

Let’s take a look at an example:

abstract class User
{
    /** @return string */
    abstract public function getPassword();
}

class MyUser extends User
{
    public function getPassword()
    {
        // return something
    }

    public function getDisplayName()
    {
        // return some name.
    }
}

class AuthSystem
{
    public function authenticate(User $user)
    {
        $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName()));
        // do something.
    }
}

In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different sub-classes of User which does not have a getDisplayName() method, the code will break.

Available Fixes

  1. Change the type-hint for the parameter:

    class AuthSystem
    {
        public function authenticate(MyUser $user) { /* ... */ }
    }
    
  2. Add an additional type-check:

    class AuthSystem
    {
        public function authenticate(User $user)
        {
            if ($user instanceof MyUser) {
                $this->logger->info(/** ... */);
            }
    
            // or alternatively
            if ( ! $user instanceof MyUser) {
                throw new \LogicException(
                    '$user must be an instance of MyUser, '
                   .'other instances are not supported.'
                );
            }
    
        }
    }
    
Note: PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case.
  1. Add the method to the parent class:

    abstract class User
    {
        /** @return string */
        abstract public function getPassword();
    
        /** @return string */
        abstract public function getDisplayName();
    }

Bug introduced by
The expression $segments of type array|null|string is not guaranteed to be traversable. How about adding an additional type check?

There are different options of fixing this problem.

  1. If you want to be on the safe side, you can add an additional type-check:

    $collection = json_decode($data, true);
    if ( ! is_array($collection)) {
        throw new \RuntimeException('$collection must be an array.');
    }
    
    foreach ($collection as $item) { /** ... */ }
    
  2. If you are sure that the expression is traversable, you might want to add a doc comment cast to improve IDE auto-completion and static analysis:

    /** @var array $collection */
    $collection = json_decode($data, true);
    
    foreach ($collection as $item) { /** .. */ }
    
  3. Mark the issue as a false-positive: Just hover the remove button, in the top-right corner of this issue for more options.

This method seems to be duplicated in your project.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.
