php地址栏传中文$_GET下来后乱码,urlencode和urldecode用法详解
url编码
语法: string urlencode(string str);
返回值: 字符串
函数种类: 编码处理
例如:

复制代码 代码如下:

$ChineseName="我的名字,是中文的哦";
$EncodeStr=urlencode($ChineseName);
echo "我的名字";
?>

url解码
还原 URL 编码字符串。
语法: string urldecode(string str);
返回值: 字符串
函数种类: 编码处理
例如:
对前面传过来的中文进行处理显示
复制代码 代码如下:

$DecodeStr=urldecode($_GET['name']);//你可能不用解码都可以,因为浏览器会自动帮你解码
echo $DecodeStr;
?>

关于php用get方法从url上获得的中文乱码问题

使用$gonghui = iconv("gb2312","UTF-8",$gonghui);另一方法代码
/**
* 多字节字符串编码转换函数
*
* @param string str 需要进行编码转换的字符串
* @param string to_encoding 指定转换为某种编码,如:gb2312、gbk、utf-8等
* @param mixed from_encoding 混合指定原来字串的编码,如:同时指定 JIS, eucjp-win, sjis-win 混合编码
* @return string
string mb_convert_encoding ( string str, string to_encoding [, mixed from_encoding] )
**/
mb_convert_encoding 函数为php内部多字节字符串编码转换函数,可以在有需要的使用场合,几乎支持所有编码。PHP  >= 4.0.6、 5 版本支持。

直接获取 reg.php?gh=某某;

 //工会登入参

$gonghui = $_GET['gh'];

获得的$gonghui 为gb2312编码 输出到utf-8网页上显示乱码

改成

 //工会登入参数
 $gonghui = $_GET['gh'];
 $gonghui = mb_convert_encoding($gonghui, "UTF-8", "gb2312");

 就显示正常了

对整个页面进行转换

该方法适用所有编码环境。这样把前128个字符以外(显示字符)的字符集都用   NCR(Numeric character reference,如“汉字”将转换成“汉字”这种形式)来表示,这样的编码在任意编码环境下页面都能正 常显示。

在php文件的头部加上下面三行代码:

复制代码 代码如下:

mb_internal_encoding("gb2312");  // 这里的gb2312是你网站原来的编码    
mb_http_output("HTML-ENTITIES");    
ob_start('mb_output_handler'); 

使用mb_convert_encoding 函数需启用PHP 的mbstring (multi-byte string)扩展。

如果没有没有开启php的mbstring扩展,则需要做如下设置,让php支持该扩展。

1、windows 服务器环境
编辑 php.ini 文件,将; extension=php_mbstring.dll 前面的 ; 去掉,重启网页服务器。

2、Linux服务器环境
在编译配置时加入 --enable-mbstring=cn 编译参数,再进行PHP的编译安装。

其它网友的第三个参考方法:
//方法一 urldecode
$url = 'aaa.php?region='.urldecode("四川省");
aaa

//方法二base64_encode


$test="四川省";
$test1=base64_encode($test);
echo 'aaa ';
?>

另一页面使用base64_decode解开

base64_decode($region);

//方法三让服务器支持中文

[root@dhcp ~]# locale

lang=zh_cn.utf-8
lc_ctype="zh_cn.utf-8"
lc_numeric="zh_cn.utf-8"
lc_time=c
