1介绍mb_convert_encoding( $str, $encoding1,$encoding2 )$str,要转换编码的字符串$encoding1,目标编码,如utf-8,gbk,大小写均可$encoding2,原编码,如utf-8,gbk,大小写均可2实例1<?php$str="编码";echo mb_convert_encoding($str, "UTF-8"); //编码转换为utf-8?>3实例2<?php$str="编码";echo mb_convert_encoding($str, "UTF-8", "GBK"); //已知原编码为GBK,转换为utf-8?>4实例3<?php$str="编码";echo mb_convert_encoding($str, "UTF-8", "auto"); //未知原编码,通过auto自动检测后,转换编码为utf-8?>URL:http://www.bianceng.cn/webkf/PHP/201410/45960.htm
