php通過header頭允許多個域名跨域

$domains = [
    'http://www.aaa.com',
    'http://www.bbb.com'
];

foreach ($domains as $v) {
    header('Access-Control-Allow-Origin:'.$v);
}


if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
    header('Access-Control-Allow-Headers:x-requested-with,content-type,token');
    exit("ok");

}
