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

Source https://phpmd.org/rules/codesize.html#toomanypublicmethods

Avoid unused parameters such as '$mode'.
Open

    public function setFetchMode($mode)

UnusedFormalParameter

Since: 0.2

Avoid passing parameters to methods or constructors and then not using those parameters.

Example

class Foo
{
    private function bar($howdy)
    {
        // $howdy is not used
    }
}

Source https://phpmd.org/rules/unusedcode.html#unusedformalparameter

Avoid assigning values to variables in if clauses and the like (line '154', column '14').
Open

    public function nextResult()
    {
        if (($result = $this->_statement->nextRowset()) !== false) {
            $this->_index = -1;
        }

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
            // ...
        }
    }
}
