为什么不呢

public static $CURRENT_TIME = time() + 7200;

工作(错误):

解析错误:语法错误,意外'('

但

class Database {
  public static $database_connection;

  private static $host = "xxx";
  private static $user = "xxx";
  private static $pass = "xxx";
  private static $db = "xxx";

  public static function DatabaseConnect(){
    self::$database_connection = new mysqli(self::$host,self::$user,self::$pass,self::$db);
    self::$database_connection->query("SET NAMES 'utf8'");
    return self::$database_connection;
  }
}

确实有效.

我是OOP的新手,我很困惑.
