## Why is this an issue?

The `var` keyword in PHP was historically used to declare class properties with default public visibility. However, its usage is discouraged as it lacks clarity and explicit visibility declaration.

Instead, PHP introduced the keywords `public`, `protected`, and `private` to clearly define the visibility of class properties. This enhances code readability and maintainability, as it becomes easier to understand and control access to class members. Additionally, using the keywords for explicit visibility helps prevent unintended modifications or security vulnerabilities that may arise from the ambiguity of the `var` keyword.

### Noncompliant code example

    <?php
    class Foo
    {
        var $bar = 1;
    }

### Compliant solution

    <?php
    class Foo
    {
        public $bar = 1;
    }
