Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

Avoid using static access to class 'UserModel' in method 'loadCurrent'. Open
if ($user = UserModel::getLoggedIn()) {
- Read upRead up
- Exclude checks
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();
}
}
Source https://phpmd.org/rules/cleancode.html#staticaccess

IfStatementAssignment
Since: 2.7.0
Assignments in if clauses and the like are considered a code smell. Assignments in PHP return the right operand as their result. In many cases, this is an expected behavior, but can lead to many difficult to spot bugs, especially when the right operand could result in zero, null or an empty string and the like.
Example
class Foo
{
public function bar($flag)
{
if ($foo = 'bar') { // possible typo
// ...
}
if ($baz = 0) { // always false
// ...
}
}
}

The method addItem uses an else expression. Else clauses are basically not necessary and you can simplify the code by not using them. Open

}

ElseExpression
Since: 1.4.0
An if expression with an else branch is basically not necessary. You can rewrite the conditions in a way that the else clause is not necessary and the code becomes simpler to read. To achieve this, use early return statements, though you may need to split the code it several smaller methods. For very simple assignments you could also use the ternary operations.
Example
class Foo
{
public function bar($flag)
{
if ($flag) {
// one branch
} else {
// another branch
}
}
