php 中文编码的转换之mb_convert_encoding()函数
在php中编码一直是开发人员的头痛的事情，但是如果我们有php的编码函数就不一样了，下面是介绍一个中文编码的处理函数。
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
实例1,代码如下:
- <?php
- $str='电影618:http://www.phpfensi.com';
- echo mb_convert_encoding($str, "UTF-8"); //编码转换为utf-8
- ?>
实例2,代码如下:
- <?php
- $str='电影618:http://www.phpfensi.com';
- echo mb_convert_encoding($str, "UTF-8", "GBK"); //已知原编码为GBK，转换为utf-8
- ?>
实例3,代码如下:
- <?php
- $str='电影618:http://www.phpfensi.com';
- echo mb_convert_encoding($str, "UTF-8", "auto"); //未知原编码，通过auto自动检测后，转换编码为utf-8
- ?>
实例4,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");
- ?>
