PHP获取搜索引擎关键字来源的函数(支持百度和谷歌等搜索引擎)

前端之家收集整理的这篇文章主要介绍了PHP获取搜索引擎关键字来源的函数(支持百度和谷歌等搜索引擎)前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

最近遇到一个项目,客户需要一个功能,一个商品销售下单需要知道用户下单是从哪个途径来的,认为客服软件(53客服)和站长统计只能满足工作时间,及晚上下班和周六日休息,客服不在线,用户下单会不知道该订单的具体来源,所以嘛,又只能通过网站功能增加一字段,获取来源关键字,如何获取来源关键字,代码发在下面,里面包含(百度、谷歌、雅虎、搜狗、搜搜、必应、有道)几大搜索引擎的获取方法代码中均注明,希望对你有帮助,分享一下 代码如下:
<div class="codetitle"><a style="CURSOR: pointer" data="3449" class="copybut" id="copybut3449" onclick="doCopy('code3449')"> 代码如下:

<div class="codebody" id="code3449">

有一点要记住,由于各搜索引擎的页面编码不一样,有的是GBK,有的是UTF8,所以在获取时会有不同对字符编码的转换
