Avoid variables with short names like $if. Configured minimum length is 3.
Short variable names may make your code harder to understand. Variable names should
be self-descriptive. This check looks for variable names who are shorter than
a configured minimum.

The expression return array('if' => $th...'else' => $this->else); seems to be an array, but some of its elements' types (null) are incompatible with the return type of the parent method PHPSA\ControlFlow\Node\AbstractNode::getSubBlocks of type PHPSA\ControlFlow\Block[].
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. This principle also belongs to the
SOLID principles
for object oriented design.
Our function my_function expects a Post object, and outputs the author
of the post. 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.
