    StaticAccess

    Since: 1.4.0

    Static access causes unexchangeable dependencies to other classes and leads to hard to test code. Avoid using static access at all costs and instead inject dependencies through the constructor. The only case when static access is acceptable is when used for factory methods.

    The method Interpolate uses an else expression. Else clauses are basically not necessary and you can simplify the code by not using them.

    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
