在一个类中混合使用静态和非静态方法是否可以接受？

Question

I have a relatively simple question, and although there are many posts about it on Google, I cannot find a single one that simply answers the question.

So the short question is "Is it acceptable to mix static and non static methods in one class?". I guess I am really asking "is it good practice to stick with one type of method", or "are there things to consider when using both".

For example, If I was building a class to cope with food in my fridge, which of the following (or what else) would be the best approach

Example 1:

Class Food
{
    public function __construct( $itemName, $itemDescription )
    {
        .... some code for a new item of food ....
    }

    public static function getAllFood()
    {
        .... some code to get all the items in my fridge ....
    }
}

$food = new Food( "apple", "Nice juicy Pink Lady apple" );
Food::getAllFood();

Or Example 2:

Class Food
{
    public function __construct( $itemName, $itemDescription )
    {
        .... some code for a new item of food ....
    }

    public function getAllFood()
    {
        .... some code to get all the items in my fridge ....
    }
}

$food = new Food( "apple", "Nice juicy Pink Lady apple" );
$food->getAllFood();

Thanks in advance
