Should the type for parameter

This check looks for It makes a suggestion as to what type it considers more descriptive. Most often this is a case of a parameter that can be null in addition to its declared types. ![]() |

It seems like
$cb defined by parameter $cb on line 56 can also be of type null ; however, PHPDaemon\Structures\StackCallbacks::push() does only seem to accept callable , maybe add an additional type check?
This check looks at variables that have been passed in as parameters and are passed out again to other methods. If the outgoing method call has stricter type requirements than the method itself, an issue is raised. An additional type check may prevent trouble. ![]() |

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.
