PHP中静态变量的使用方法实例分析

public static $endpoint,$accessKeyId,$accessKeySecret,$bucket;

protected function _initialize() {  self::$endpoint = C('OSS_ENDPOINT');  self::$accessKeyId = C('OSS_ACCESS_ID');  self::$accessKeySecret = C('OSS_ACCESS_KEY');  self::$bucket = C('OSS_TEST_BUCKET');}

public static function getOssClient(){  try {   $ossClient = new OssClient(self::$accessKeyId, self::$accessKeySecret, self::$endpoint, false);  } catch (OssException $e) {   printf(__FUNCTION__ . "creating OssClient instance: FAILED/n");   printf($e->getMessage() . "/n");   return null;  }  return $ossClient;}
