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"

The method formatArg() has an NPath complexity of 7128. The configured NPath complexity threshold is 200. Open

NPathComplexity
Since: 0.1
The NPath complexity of a method is the number of acyclic execution paths through that method. A threshold of 200 is generally considered the point where measures should be taken to reduce complexity.
Example
class Foo {
function bar() {
// lots of complicated code
}
}

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 == $b2) {
fiddle();
} else {
fiddle();
}
5 } elseif ($c == $d) {
6 while ($c == $d) {
fiddle();
}
7 } elseif ($e == $f) {
8 for ($n = 0; $n < $h; $n++) {
fiddle();
}
} else {
switch ($z) {
9 case 1:
fiddle();
break;
10 case 2:
fiddle();
break;
11 case 3:
fiddle();
break;
default:

break;

The method formatControlChars uses an else expression. Else clauses are basically not necessary and you can simplify the code by not using them. Open
else {
$result .= $string{$i};
}

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
}
}
}
