PHP function to obtain the source of search engine keywords (supports search engines such as Baidu and Google)_PHP tutorial

I recently encountered a project where the customer needed a function. To place an order for a product sales, you need to know which channel the user placed the order from. I think that the customer service software (53 customer service) and webmaster statistics can only meet the needs of working hours, evening get off work and weekdays. We are closed for six days and the customer service is not online. Users placing orders will not know the specific source of the order. Therefore, we can only add a field to obtain the source keyword through the website function. How to obtain the source keyword, the code is posted below. It contains the acquisition methods of several major search engines (Baidu, Google, Yahoo, Sogou, Soso, Bing, Youdao). They are all marked in the code. I hope it will be helpful to you. Share

The code is as follows :

Copy code The code is as follows:

//Get the inbound data from search engines Keywords
function get_keyword($url,$kw_start)
{
$start=stripos($url,$kw_start);
$url=substr($url,$start+strlen($ kw_start));
$start=stripos($url,'&');
if ($start>0)
{
$start=stripos($url,'&');
$s_s_keyword=substr($url,0,$start);
}
else
{
$s_s_keyword=substr($url,0);
}
return $s_s_keyword;
}

One thing to remember is that since the page encoding of each search engine is different, some are GBK and some are UTF8, so there will be different character encoding conversions when retrieving
