mb_convert_encoding function for PHP internal Multi-byte string encoding conversion function, can be used in the case of code conversion, such as: To solve the GB2312 encoding environment using AJAX generated Chinese characters garbled problem. Support for almost all encodings, version support PHP 4 >= 4.0.6, PHP 5.
Function Prototypes:
/**
* Multi-byte string encoding conversion function

Echo mb_convert_encoding ("You Are my good friend", "gb312", "utf-8");
?>

3, the entire page to convert

This method applies to all coding environments. The character set other than the first 128 characters (display character) is used NCR (Numeric character reference, such as "kanji" will be converted to "& #27721;& #23383;" This form) to indicate that the code in any encoding environment, the page can be displayed normally.

The method is to add the following three lines of code to the header of the PHP file:
Mb_internal_encoding ("gb2312"); The gb2312 here is the original code of your website.
Mb_http_output ("Html-entities");
Ob_start (' Mb_output_handler ');

However, using the Mb_convert_encoding function requires PHP mbstring (multi-byte String) extension to be enabled.
