php - 如果或倍数

Question

我正在尝试查看 mysql 存储的状态，看看它们是否符合我的代码在此处的条件:

$stater = $this->state;
if ($stater == 'WA' OR 
$stater == 'BC' OR 
$stater == 'CA' OR
 $stater == 'NV' OR 
$stater == 'AZ' OR 
$stater == 'ID' OR 
$stater == 'OR' OR 
$stater == 'UT' OR 
$stater == 'MT' OR 
$stater == 'NM' OR 
$stater = 'wa' OR 
$stater = 'bc' OR 
$stater = 'CA' OR 
$stater = 'nv' OR 
$stater = 'az' OR 
$stater = 'id' OR 
$stater = 'or' OR 
$stater = 'ut' OR 
$stater = 'mt' OR 
$stater = 'nm'){               
                 $division = "West";
               }
           else{
           $division="";
               }

无论如何它都在向西返回:\我尝试将 ='s 更改为 =='s 我尝试将每个分隔或放入其自己的括号中 ex if( ($stater='ca') || ($ stater='nm')) 等等，但仍然没有任何效果。任何帮助将不胜感激

问题是您使用的是 = 而不是 ==，所以 $stater 总是以 结尾WA'。也就是说，使用数组和 in_array() 代替可能更简洁:

$west = array('WA', 'BC', 'CA', ...);
if (in_array($stater, $west)) {
    $division = 'west';
}
