# 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"

#### Function prepare has a Cognitive Complexity of 17 (exceeds 5 allowed). Consider refactoring. 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) {

# BooleanArgumentFlag

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

#### Avoid assigning values to variables in if clauses and the like (line '764', column '20'). Open

# 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
// ...
}
}
}
