Comprehensibility Bug introduced by
It seems like you call parent on a different method (isTracked() instead of refreshItem()). Are you sure this is correct? If so, you might want to change this to $this->isTracked().

This check looks for a call to a parent method whose name is different than the method from which it is called.

Consider the following code:

class Daddy
{
    protected function getFirstName()
    {
        return "Eidur";
    }

    protected function getSurName()
    {
        return "Gudjohnsen";
    }
}

class Son
{
    public function getFirstName()
    {
        return parent::getSurname();
    }
}

The getFirstName() method in the Son calls the wrong method in the parent class.

Documentation introduced by
The property title does not exist on object<allejo\stakx\Object\PageView>. Since you implemented __get, maybe consider adding a @property annotation.

Since your code implements the magic getter _get, this function will be called for any read access on an undefined variable. You can add the @property annotation to your class or interface to document the existence of this variable.

<?php

/**
 * @property int $x
 * @property int $y
 * @property string $text
 */
class MyLabel
{
    private $properties;

    private $allowedProperties = array('x', 'y', 'text');

    public function __get($name)
    {
        if (isset($properties[$name]) && in_array($name, $this->allowedProperties)) {
            return $properties[$name];
        } else {
            return null;
        }
    }

    public function __set($name, $value)
    {
        if (in_array($name, $this->allowedProperties)) {
            $properties[$name] = $value;
        } else {
            throw new \LogicException("Property $name is not defined.");
        }
    }

}

If the property has read access only, you can use the @property-read annotation instead.

Of course, you may also just have mistyped another name, in which case you should fix the error.

See also the PhpDoc documentation for @property.

Compatibility introduced by
$pageView of type object<allejo\stakx\Object\PageView> is not a sub-type of object<allejo\stakx\Object\RepeaterPageView>. It seems like you assume a child class of the class allejo\stakx\Object\PageView to be always present.

This check looks for parameters that are defined as one type in their type hint or doc comment but seem to be used as a narrower type, i.e an implementation of an interface or a subclass.

Consider changing the type of the parameter or doing an instanceof check before assuming your parameter is of the expected type.

Maybe you want to instanceof check for one of these explicitly?

    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();
    }

It seems like you code against a specific sub-type and not the parent class allejo\stakx\Object\PageView as the method getRepeaterPermalinks() does only exist in the following sub-classes of allejo\stakx\Object\PageView: allejo\stakx\Object\RepeaterPageView. 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.

Bug introduced by
The expression $pageView->getRedirects() of type null|array<integer,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.
