Code conversion Functions Iconv () and mb_convert_encoding in PHP

In PHP to convert the code can be used Iconv () and mb_convert_encoding, these 2 functions are not the default PHP function, installation method see Baidu, here is the main difference between the two.

Some characters are encoded under UTF8 and are not encoded under GBK, which can cause problems when converting. Mb_convert_encoding When this happens, the non-encoded characters are turned into \0x00\0x80, and iconv is broken when it encounters a special character, but we can add "//ignore" after its second argument, It ignores the non-encoded characters that are encountered.
