php - Is it acceptable to mix static and non static methods in one class? -

i have relatively simple question, , although there many posts on google, cannot find single 1 answers question.

so short question "is acceptable mix static , non static methods in 1 class?". guess asking "is practice stick 1 type of method", or "are there things consider when using both".

for example, if building class cope nutrient in fridge, of next (or else) best approach

example 1:

class nutrient { public function __construct( $itemname, $itemdescription ) { .... code new item of nutrient .... } public static function getallfood() { .... code items in fridge .... } } $food = new food( "apple", "nice juicy pinkish lady apple" ); food::getallfood();

or illustration 2:

class nutrient { public function __construct( $itemname, $itemdescription ) { .... code new item of nutrient .... } public function getallfood() { .... code items in fridge .... } } $food = new food( "apple", "nice juicy pinkish lady apple" ); $food->getallfood();

thanks in advance

q: acceptable mix static , non-static methods in class?

a: sure, long as:

1) sense both methods logically belong in same class, and

2) static method(s) can/should called independent of class instance.

the best rule of thumb utilize static methods when phone call stateless.
