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 up uses an else expression. Else clauses are basically not necessary and you can simplify the code by not using them. Open
Open
} else {
$table = $schema->getTable('skill_rel_course');
if (!$table->hasForeignKey('FK_E7CEC7FA5585C142')) {
$this->addSql('DELETE FROM skill_rel_course WHERE skill_id NOT IN (SELECT id FROM skill)');

ElseExpression
Since: 1.4.0
An if expression with an else branch is basically not necessary. You can rewrite the conditions in a way that the else clause is not necessary and the code becomes simpler to read. To achieve this, use early return statements, though you may need to split the code it several smaller methods. For very simple assignments you could also use the ternary operations.
Example
class Foo
{
public function bar($flag)
{
if ($flag) {
// one branch
} else {
// another branch
}
}
}Source https://phpmd.org/rules/cleancode.html#elseexpression
