Function: PHP converts strings from GBK to UTF8 character set iconv

1. Introduction to iconv ()

The iconv function converts one known character set file into another known character set file. For example: convert from GB2312 to UTF-8.

The iconv function is built into php5, and the GB character set is turned on by default.

Iconv will make an error when converting the character "-" to gb2312. The solution is to add "/ / IGNORE" after the encoding to be converted, that is, after the second argument of the iconv function. As follows:

Iconv ("UTF-8", "GB2312//IGNORE", $data)

Ignore means to ignore the conversion error, and without the ignore parameter, all strings following that character cannot be saved.
