EvalExpression
Since: 0.2
An eval-expression is untestable, a security risk and bad practice. Therefore it should be avoided. Consider to replace the eval-expression with regular code.
Example
class Foo {
public function bar($param) {
if ($param === 42) {
eval('$param = 23;');
}
}
}

The class View has 19 public methods. Consider refactoring View to keep number of public methods under 10. Open

TooManyPublicMethods
Since: 0.1
A class with too many public methods is probably a good suspect for refactoring, in order to reduce its complexity and find a way to have more fine grained objects.
By default it ignores methods starting with 'get' or 'set'.
Example

Function renderPhpFile
has a Cognitive Complexity of 12 (exceeds 5 allowed). Consider refactoring. Open
public function renderPhpFile($_file_, $_params_ = [])
{
$_obInitialLevel_ = ob_get_level();
ob_start();
ob_implicit_flush(false);

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"

// e.g. "@app/views/main"

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:

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

*/
private $x = null;
/**
* @var \foo\bar\Y
*/
private $y = null;
/**
* @var \foo\bar\Z

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
}

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) {
}
}

Avoid assigning values to variables in if clauses and the like (line '188', column '20'). Open
protected function findViewFile($view, $context = null)

$file = Yii::getAlias($view);

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
// ...
}
}
}
