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"

Method run
has 72 lines of code (exceeds 25 allowed). Consider refactoring. Open
public function run(array $cliArguments, $interval = 1000000, $timeout = null, callable $callback = null)
{
$watcher = new Watcher();

Avoid too many return
statements within this method. Open
return $watcher->watch($arguments, $interval, $timeout, $callback);
The method run() has 100 lines of code. Current threshold is set to 100. Avoid really long methods. 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
}
}

The method run() has a Cyclomatic Complexity of 19. The configured cyclomatic complexity threshold is 10. Open

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:
fiddle();
break;
}
}

The method run() contains an exit expression. Open
exit(0);
- Read upRead up
- Exclude checks
ExitExpression
Since: 0.2
An exit-expression within regular code is untestable and therefore it should be avoided. Consider to move the exit-expression into some kind of startup script where an error/exception code is returned to the calling environment.
Example
class Foo {
public function bar($param) {
if ($param === 42) {
exit(23);
}
}
}
