PHP detects the current character encoding and transcoding-php Tutorial

PHP detects the current character encoding and transcode 1. detects the current string encoding and changes the encoding to UTF-8

1. obtain the encoding of the current string.

$ Encode = mb_detect_encoding ($ str, array ("ASCII", 'utf-8', "GB2312", "GBK", 'big5 '));

2. change the character encoding to UTF-8.

$ Str_encode = mb_convert_encoding ($ str, 'utf-8', $ encode );
