ThinkPHP uses the GET method to GET the Chinese parameter query result-less solution _ php instance

This article describes how ThinkPHP uses the GET method to obtain the query results of Chinese parameters. if you want to use ThinkPHP as a tags tag, a problem occurs, parameters can be obtained, but no results can be found. The data found in the database exists. Where is the problem?

Such as http:/response

The parameter is encoded by urlencode (). The urldecode () function is used for decoding, and no result is returned for further query.
Then test the iconv () function, and the result is successful.

The default browser encoding is GB2312, and this project uses UTF-8 encoding.
The following describes the error code and the corrected code:

$ Kw = $ _ GET ['_ URL _'] ['2']; // the error code contains parameters that can be obtained on iis but cannot be queried. $ Kw = iconv ("gb2312", "UTF-8", $ _ GET ['_ URL _'] ['2']); // encoded, results that can be queried.

In addition,This method is only applicable to the iis environment..
Note that when $ _ GET receives parameters, the urldecode transcoding function is available. you do not need to perform the urldecode decoding operation!
