Php localhost配置

Question

我需要配置此常量，适用于在线服务器：

localhost/_/

在我的localhost上工作。本地网站的本地网址是

define("APP_DIR","/_");

我这样设置但不起作用：

 @numbers = [1,2,3,4,5,6,7,8,9]

  @numbers.each do |n|              

    if @order.card_type"n" != "none" 
      notes +=  "\n\nCard 1: " + @order.card_type1 + "\nPaper Weight: " + @order.paper_weight1 + "\nQuantity: " + @order.quantity1 + "\nInk Color #1: " + @order.ink_color11 + "\nInk Color #2: " + @order.ink_color12 + "\nWording: " + @order.wording1 + "\nReturn Address Printing: " + @order.return_address1 + "\nGuest Address Printing: " + @order.guest_address1.to_s + "\nEnvelope Liners: " + @order.envelope_liners1                 
    end               

  end
