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"

CyclomaticComplexity
Since: 0.1
Complexity is determined by the number of decision points in a method plus one for the method entry. The decision points are 'if', 'while', 'for', and 'case labels'. Generally, 1-4 is low complexity, 5-7 indicates moderate complexity, 8-10 is high complexity, and 11+ is very high complexity.
Example
// Cyclomatic Complexity = 11
class Foo {
1 public function example() {
2 if ($a == $b) {
3 if ($a1 == $b1) {
fiddle();
4 } elseif ($a2 == $b2) {
fiddle();
} else {

ErrorControlOperator
Error suppression should be avoided if possible as it doesn't just suppress the error, that you are trying to stop, but will also suppress errors that you didn't predict would ever occur. Consider changing error_reporting() level and/or setting up your own error handler.
Example
function foo($filePath) {
$file = @fopen($filPath); // hides exceptions
$key = @$array[$notExistingKey]; // assigns null to $key
}

The method userExists has a boolean flag argument $throw_exception, which is a certain sign of a Single Responsibility Principle violation. Open
public function userExists($username, $throw_exception = false)
- Read upRead up
- Exclude checks
BooleanArgumentFlag
Since: 1.4.0
A boolean flag argument is a reliable indicator for a violation of the Single Responsibility Principle (SRP). You can fix this problem by extracting the logic in the boolean flag into its own class or method.
Example
class Foo {
public function bar($flag = true) {
}
}
Source https://phpmd.org/rules/cleancode.html#booleanargumentflag
The method authenticate uses an else expression. Else clauses are basically not necessary and you can simplify the code by not using them. Open
} else {
// group membership is not required and user is valid
return true;
}
- Read upRead up
- 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
}
}
}

Avoid using empty try-catch blocks in getRoles. Open

EmptyCatchBlock
Since: 2.7.0
Usually empty try-catch is a bad idea because you are silently swallowing an error condition and then continuing execution. Occasionally this may be the right thing to do, but often it's a sign that a developer saw an exception, didn't know what to do about it, and so used an empty catch to silence the problem.
Example
class Foo {
public function bar()
{
try {
// ...
} catch (Exception $e) {} // empty catch block
}
}
