php中的字符编码转换函数的用法
一般来说,在网页程序中,尤其是涉及到数据库的`读出过程中,往往最恼火的就是字符编码的问题,php4.0.6以上的版本提供了mb_convert_encoding 可以方便的转换编码。
具体如下:
复制代码 代码如下:<?php
/* Convert internal character encoding to SJIS */
$str = mb_convert_encoding($str, "SJIS");
/* Convert EUC-JP to UTF-7 */
$str = mb_convert_encoding($str, "UTF-7", "EUC-JP");
/* Auto detect encoding from JIS, eucjp-win, sjis-win, then convert str to UCS-2LE */
$str = mb_convert_encoding($str, "UCS-2LE", "JIS, eucjp-win, sjis-win");
/* "auto" is expanded to "ASCII,JIS,UTF-8,EUC-JP,SJIS" */
$str = mb_convert_encoding($str, "EUC-JP", "auto");
?>
比如要把gb2312的字符串转为utf-8的,可以用如下方法:
复制代码 代码如下:$str=mb_convert_encoding($str,"UTF-8","GB2312")
