php中的字符編碼轉(zhuǎn)換函數(shù)的用法

  一般來(lái)說(shuō),在網(wǎng)頁(yè)程序中,尤其是涉及到數(shù)據(jù)庫(kù)的`讀出過(guò)程中,往往最惱火的就是字符編碼的問(wèn)題,php4.0.6以上的版本提供了mb_convert_encoding 可以方便的轉(zhuǎn)換編碼。

  具體如下:

  復(fù)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(zhuǎn)為utf-8的,可以用如下方法:

  復(fù)制代碼 代碼如下:$str=mb_convert_encoding($str,"UTF-8","GB2312")
