php中的字符編碼轉換函數的用法
一般來說,在網頁程序中,尤其是涉及到數據庫的`讀出過程中,往往最惱火的就是字符編碼的問題,php4.0.6以上的版本提供了mb_convert_encoding 可以方便的轉換編碼。
具體如下:
復制代碼 代碼如下:<?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的字符串轉為utf-8的,可以用如下方法:
復制代碼 代碼如下:$str=mb_convert_encoding($str,"UTF-8","GB2312")
