A long parameter list can indicate that a new structure should be created to wrap the numerous parameters or that the function is doing too many things.
Noncompliant Code Example
With a maximum number of 4 parameters:
function doSomething($param1, $param2, $param3, $param4, $param5) { ... }
Compliant Solution
function doSomething($param1, $param2, $param3, $param4) { ... }

CouplingBetweenObjects
Since: 1.1.0
A class with too many dependencies has negative impacts on several quality aspects of a class. This includes quality criteria like stability, maintainability and understandability
Example
class Foo {
/**
* @var \foo\bar\X
*/
private $x = null;
/**
* @var \foo\bar\Y
*/
private $y = null;
/**
* @var \foo\bar\Z
*/
private $z = null;
public function setFoo(\Foo $foo) {}
public function setBar(\Bar $bar) {}
public function setBaz(\Baz $baz) {}
/**
* @return \SplObjectStorage
* @throws \OutOfRangeException
* @throws \InvalidArgumentException
* @throws \ErrorException

public function process(\Iterator $it) {}

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();
}
}

The method answerQuestion uses an else expression. Else clauses are basically not necessary and you can simplify the code by not using them. Open
} else {
$answer = $this->answerRepository->getById(Uuid::fromString($answerId));
if (null === $answer) {
throw new \InvalidArgumentException(
'No answer with id "'.$answerId.'"'

- Exclude checks
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
}
}
}

Define a constant instead of duplicating this literal "No quiz with id " 3 times. Open
'No quiz with id '.$quizId.'.',
- Read upRead up
- Exclude checks
Duplicated string literals make the process of refactoring error-prone, since you must be sure to update all occurrences.
On the other hand, constants can be referenced from many places, but only need to be updated in a single place.
Noncompliant Code Example
With the default threshold of 3:
function run() { prepare('action1'); // Non-Compliant - 'action1' is duplicated 3 times execute('action1'); release('action1'); }
Compliant Solution
ACTION_1 = 'action1'; function run() { prepare(ACTION_1); execute(ACTION_1); release(ACTION_1); }
Exceptions
To prevent generating some false-positives, literals having less than 5 characters are excluded.
