3. php or html file encoding: use editplus to open the php file or html file. if the database and page encoding are gbk, the encoding here is ansi. if the database and page encoding are UTF-8, then UTF-8 is also used. 4. the data transmitted in javascript or flash is UTF-8 encoded. Note that the data transmitted in javascript or flash is UTF-8 encoded. if the database and page encoding are gbk, transcoding is required, then write the data to the database. Iconv ('utf-8', 'gbk', $ content); 5.

Second, use the header () function to send the original http header, which can contain more content. encoding is only one of them. Third, in some cases, do not display any content on the webpage, but notify the browser of the encoding used for subsequent actions.
