How to correctly handle PHPAjax garbled characters. Because XMLHTTP uses Unicode encoding to upload data, and generally uses gb2312 as the page, garbled characters are generated when the page is displayed. When retrieving the page, XMLHttp returns UTF-8 encoding.Because XMLHTTP uses Unicode encoding to upload data, and generally uses gb2312 as the page, garbled characters are generated when the page is displayed. When the page is obtained, XMLHttp returns UTF-8 encoding, which causes garbled characters in the display.

One of the solutions to PHP Ajax garbled code is to display the declaration as GB2312 in the PHP file.

Header ("Content-Type: text/html; charset = GB2312 ");

Transcode the Chinese characters sent to the server.

As follows:

$ _ POST ["content"] = iconv ("UTF-8", "gb2312", $ _ POST ["content"]);

This can solve the PHP Ajax garbled problem.

Method 2, is using UTF-8 encoding. I will not talk about it here.
