最近遇到一個項目，客戶需要一個功能，一個商品銷售下單需要知道用戶下單是從哪個途徑來的，認為客服軟件（53客服）和站長統計只能滿足工作時間，及晚上下班和周六日休息，客服不在線，用戶下單會不知道該訂單的具體來源，所以嘛，又只能通過網站功能來增加一字段，獲取來源關鍵字，如何獲取來源關鍵字，代碼發在下面，里面包含（百度、谷歌、雅虎、搜狗、搜搜、必應、有道）幾大搜索引擎的獲取方法，代碼中均注明，希望對你有幫助，分享一下

代碼如下：

復制代碼代碼如下:

<?php
//獲取來自搜索引擎入站時的關鍵詞
function get_keyword($url,$kw_start)
{
$start=stripos($url,$kw_start);

if ($start>0)
{
$start=stripos($url,'&');
$s_s_keyword=substr($url,0,$start);
}
else
{
$s_s_keyword=substr($url,0);
}
return $s_s_keyword;
}

有一點要記住，由于各搜索引擎的頁面編碼不一樣，有的是GBK,有的是UTF8,所以在獲取時會有不同對字符編碼的轉換
