我们的开发人员为 php 提供了一个脚本，用于从我们的数据库中生成畅销书列表，但是我们需要它处于冷融合状态！

有没有一种简单的转换方法或者需要完全重写？

提前感谢您的任何建议:-)

代码转换问题往往不会长时间保持开放状态，因为它们被视为懒惰。因此，这里有一些参考资料可以帮助您入门。我不是 PHP 专业人士，但在快速浏览您的代码后，我认为此链接列表将为您提供一个良好的开端。

为了不为你做你的工作并给你学习的机会，我将提供一些示例而不是整个代码，以便你了解你的 PHP 适合 CF 的位置。这也是标签版本，而不是脚本版本。 

<cffunction name = "CWgetBestSelling" ...>
  <cfargument name = "max_products" default = "5" ...>
  <cfargument ...>

  <cfset var local.productQuery = "">
  <cfset var local.returnQuery = "">
  <cfset ...>
  <cfset ...>

  <cfquery name = "q_productQuery " datasource = "yourDatasource">
    SELECT 
      count(*) as prod_counter,
      p.product_id,
      p.product_name,
      p.product_preview_description,
      p.product_date_modified
    FROM 
      cw_products p
      INNER JOIN cw_order_skus o
      INNER JOIN cw_skus s
    WHERE 
          o.ordersku_sku = s.sku_id
      AND s.sku_product_id = p.product_id
      AND NOT p.product_on_web = 0
      AND NOT p.product_archive = 1
      AND NOT s.sku_on_web = 0
    GROUP BY 
      product_id
    ORDER BY 
      prod_counter DESC
    LIMIT #arguments.max_products#
  </cfquery>

  ...
  ...
  ... 

  <cfreturn yourReturnVariable>
</cffunction>
