在静态函数php中赋值

Question

I would reuse a variable $spider_flag inside static function to include in other static function. How to do that ?

TK

 public static function start() {

 $spider_flag = false;

          if (!empty($user_agent) || strpos ($user_agent, "Googlebot") > 0) {
            $user_agent = strtolower($_SERVER['HTTP_USER_AGENT']);

            if (!empty($user_agent)) {
              foreach (file(Sites/Assets/spiders.txt') as $spider) {
                if (!empty($spider)) {
                  if (strpos($user_agent, $spider) !== false) {
                    $wo_full_name = $spider;
                    $spider_flag = true;

                    break;
                  }
                }
              }
            }
          }

the other function

 public static function getResultSpiderFlag() {
      $spider_flag= ????
      return $spider_flag;

    }

Answer 1

below class definition:

public static $spider_flag;

inside function

self::$spider_flag = 'something'

or

self::$spider_flag //for the value;
