UnusedPrivateField

private $i = 5; // Unused
private $j = 6;
public function addOne()

StaticAccess
Since: 1.4.0
Static access causes unexchangeable dependencies to other classes and leads to hard to test code. Avoid using static access at all costs and instead inject dependencies through the constructor. The only case when static access is acceptable is when used for factory methods.
Example
class Foo
{
public function bar()
{
Bar::baz();
}
}

If a private
field is declared but not used in the program, it can be considered dead code and should therefore be removed. This will
improve maintainability because developers will not wonder what the variable is used for.
Noncompliant Code Example
class MyClass { private $foo = 4; //foo is unused public function compute($a) { return $a * 4; } }
Compliant Solution
class MyClass { public function compute($a) { return $a * 4; } }
