The type Slim\Container was not found. Maybe you did not declare it correctly or list all dependencies?
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
The issue could also be caused by a filter entry in the build configuration.
If the path has been excluded in your configuration, e.g. excluded_paths: ["lib/*"],
you can move it to the dependency path list as follows:


filter:
    dependency_paths: ["lib/*"]

This check compares calls to functions or methods with their respective definitions.
If the call has less arguments than are defined, it raises an issue.


If a function is defined several times with a different number of parameters, the
check may pick up the wrong definition and report false positives. One codebase
where this has been known to happen is Wordpress. Please note the @ignore annotation hint above.

The expression $fd of type integer|null is loosely compared to true; this is ambiguous if the integer can be 0. You might want to explicitly use !== null instead.
                                                                                                                                                                                                                                                            

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
In PHP, under loose comparison (like ==, or !=, or switch conditions),
values of different types might be equal.


For integer values, zero is a special case, in particular the following
results might be unexpected:


0   == false // true
0   == null  // true
123 == false // false
123 == null  // false

// It is often better to use strict comparison
0 === false // false
0 === null  // false
