Any ways to reduce the repeated patterns of code in php

Question

I have some codes here

if ($brand == "Kumiai Dairies" || $brand == "Anlene" || $brand == "Yoplait" || $brand == "Hokkaido Hidaka" 
|| $brand == "Jacob's" || $brand == "V8" || $brand == "Cow & Gate"){
do something here;
}

Is there any way to prevent repeating $brand == "xxx"??

Answer 1

是的,你可以使用in_array:

in_array($brand, array('Kumiai bla', 'Analblah', 'Whatever', ...))

Answer 2

您可以创建一个关联数组:

$brands = array(
    "Kumiai Dairies" => true,
    "Anlene" => true,
    ...
);

然后检查它

if(isset($brands[$brand])) {

}

请参阅@Corbin在@ThiefMaster答案中的评论,以解释这两种方法的不同之处.
