我也不知道是什么问题啦~~烦四了~~(关于Mcrypt)

[hodat]

我的代码:
-----------------------------
<?
$EnCoder_Key="WelCome 2 The 9 Station !@#$%";
$EnCoder_type=MCRYPT_RIJNDAEL_128; //加密类型


$string[]="我爱逆水行舟大声疾呼";
$string[]="认证介绍 精选Dump 精选文章";
$string[]="网站加速 PHP 缓冲的免费实现方法";
$string[]="用PHP写的SMTP类,支持附件(多个),";
$string[]="在编辑器中带颜色,如果您还没有";


for($i=0;$i<count($string);$i++){
$tt[]=Do_Crypt($string[$i]);
}
echo "<pre>";
print_r($tt);
echo "</pre>";

for($k=0;$k<count($tt);$k++){
$kk[]=Do_Uncrypt($tt[$k]);
}

echo "<pre>";
print_r($kk);
echo "</pre>";


function Do_Crypt($s){
global $EnCoder_Key,$EnCoder_type;

$iv = mcrypt_create_iv(mcrypt_get_iv_size($EnCoder_type,MCRYPT_MODE_ECB), MCRYPT_RAND);
$encrypted_stringa = mcrypt_encrypt( $EnCoder_type, $EnCoder_Key, trim($s), MCRYPT_MODE_CBC, $iv);
$encrypted_string = bin2hex($encrypted_stringa);
return $encrypted_string;
}

function Do_Uncrypt($s){
global $EnCoder_Key,$EnCoder_type;

$saa=trim($s);
unset($string_en);
$string_en=hex2bin($saa);
$iv = mcrypt_create_iv(mcrypt_get_iv_size($EnCoder_type,MCRYPT_MODE_ECB), MCRYPT_RAND);
$decrypted_string = mcrypt_decrypt( $EnCoder_type, $EnCoder_Key, trim($string_en), MCRYPT_MODE_CBC, $iv);
return trim($decrypted_string);
}

function hex2bin($hexdata) {

for ($i=0;$i<strlen($hexdata);$i+=2) {
$bindata.=chr(hexdec(substr($hexdata,$i,2)));
}

return $bindata;
}
?>

得到的结果~~

为什么这样啊??

望高手指点!~~~

在网页中有没有加入以下内容:
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

你用的服务器是IIS还是Aapche?

php.ini中的
default_charset = "GB2312"有没有设?

……

[hodat]

页面加了

<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

php.ini

default_mimetype = "text/html"
default_charset = "GB2312"

[shuiaaa]

default_mimetype = "text/html"
default_charset = "GB2312"
