php中的字符编码转换函数

在网页程序中，特别是设计到数据库的读出过程中，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。

<?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

$str=mb_convert_encoding($str,"UTF-8","GB2312")
