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 ?>
