It seems like you code against a concrete implementation and not the interface
Badcow\DNS\Rdata\RdataInterface as the method getTarget() does only exist in the following implementations of said interface: Badcow\DNS\Rdata\CNAME , Badcow\DNS\Rdata\DNAME , Badcow\DNS\Rdata\NS , Badcow\DNS\Rdata\PTR , Badcow\DNS\Rdata\SRV , Badcow\DNS\Rdata\URI .
Let’s take a look at an example: interface User
{
/** @return string */
public function getPassword();
}
class MyUser implements 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 implementation of User which does not have a getDisplayName() method, the code will break. Available Fixes
Note: PHP Analyzer uses reverse abstract interpretation to narrow down the types
inside the if block in such a case.
