The cause and solution of garbled Chinese parameters in GET received by PHP

A few days ago, I wrote a search function with sphinx and tested the search results with a browser, but I couldn't find any Chinese content. I use echo to output the keyword $_ GET, which shows garbled code under the page code of UTF-8, which is normal when switching to gb2312. However, sphinx only supports Chinese character search in UTF-8, so I have to solve the problem of received Chinese parameters.

Under the google on the Internet, I found an article entitled "in-depth study of Chinese parameters garbled in PHP receiving GET". It was mentioned in the article that this is due to the setting problem of the browser. If you enter Chinese parameters directly on the address bar, the browsers in the Chinese interface generally receive the parameters with the code of gbk. In cases like this, we need to use php's built-in transcoding function to deal with the coding problem:

Option 1:

$str = iconv ("gb2312", "utf-8", $str)

Option 2:

Mb_convert_encoding ($str, "utf-8", "gb2312")

If the Chinese parameter is obtained by using the text input box under the page encoding of utf-8, the page will encode it by default, so the above transcoding method is not needed in this case.

If you want to generate a link with Chinese parameter values on the page, you need to encode the Chinese characters with urlencode () under the utf-8-encoded code and then generate the link.
