Are you sure the iterator is never empty, otherwise this variable is not defined? It seems like you are relying on a variable being defined by an iteration: foreach ($a as $b) { } // $b is defined here only if $a has elements, for example if $a is array() // then $b would not be defined here. To avoid that, we recommend to set a // default value for $b. // Better $b = 0; // or whatever default makes sense in your context foreach ($a as $b) { } // $b is now guaranteed to be defined here.

If you return a value from a function or method, it should be a sub-type of the type that is given by the parent type f.e. an interface, or abstract method. This is more formally defined by the Lizkov substitution principle, and guarantees that classes that depend on the parent type can use any instance of a child type interchangably.

The base class `Post` returns a simple string and outputting a simple string will work just fine. However, the child class `BlogPost` which is a sub-type of `Post` instead decided to return an `object`, and is therefore violating the SOLID principles. If a `BlogPost` were passed to `my_function`, PHP would not complain, but ultimately fail when executing the `strtoupper` call in its body. Loading history...
