    Function isPrime has a Cognitive Complexity of 6 (exceeds 5 allowed). Consider refactoring.
    Open

    function isPrime(float $number, int $try = 0): bool
    {
        if ($try > FERMA_MAX_TRY) {
            return true;

    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"

    Avoid assigning values to variables in if clauses and the like (line '10', column '10').
    Open

    function calcGCD(int $fval, int $sval): int
    {
        list($lower, $highest) = ($fval > $sval ? [$sval, $fval] : [$fval, $sval]);
        if (($remainder = ($highest % $lower)) === 0) {
            return $lower;

    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
                // ...
            }
        }
    }

    Avoid variables with short names like $a. Configured minimum length is 3.
    Open

        $a = mt_rand(1, $number - 1);

    ShortVariable

    Since: 0.2

    Detects when a field, local, or parameter has a very short name.

    Example

    class Something {
        private $q = 15; // VIOLATION - Field
        public static function main( array $as ) { // VIOLATION - Formal
            $r = 20 + $this->q; // VIOLATION - Local
            for (int $i = 0; $i < 10; $i++) { // Not a Violation (inside FOR)
                $r += $this->q;
            }
        }
    }
