Add a field through the website function, get the source keyword, how to get the source keyword, the code is sent below, including (Baidu, Google, Yahoo, Sogou, search, Bing, Youdao) the code shows how to obtain several search engines. I hope it will be helpful to you.

Therefore, you can only add a field through the website function to obtain the source keyword and how to obtain the source keyword, the code is published below, which contains several methods for obtaining search engines (Baidu, Google, Yahoo, Sogou, sousearch, Bing, and Youdao). the code indicates that it is helpful to you, share
The code is as follows:
The code is as follows:
// Obtain keywords from the search engine

$ S_s_keyword = substr ($ url, 0, $ start );
}
Else
{
$ S_s_keyword = substr ($ url, 0 );
}
Return $ s_s_keyword;

One thing to remember is that because the page encoding of different search engines is different, some are GBK, some are UTF8, so there will be different character encoding conversions during retrieval.
