This check compares the return type specified in the @return annotation of a function or method doc comment with the types returned by the function and raises an issue if they mismatch.

array
In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code:
class MyClass { } $x = new MyClass(); $x->foo = true;
Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion:
class MyClass { public $foo; } $x = new MyClass(); $x->foo = true;
return $this;
}
