我说的是样式哦，可不是破解。废话不多说的，我用的是16进制，yahoo的是10进制（貌似）：
感谢这位朋友：http://www.phpx.com/happy/viewth ... =page%3D1#pid947632 他给了我借鉴的思路
<?php
function len($str)
{
return function_exists('mb_strlen') ? mb_strlen($str) : strlen($str);
}
function mykey($str,$key,$type=0)
{
$out = '';
$kc = md5($key);
$nk = array();
$klen = len($kc);
for($j=0;$j<$klen;$j++)
{
$nk[$j] = hexdec(substr($kc,$j,1));
}
$k=0;
switch($type)
{
case 0: //加密
$slen = len($str);
for($i=0;$i<$slen;$i++)
{
$out .= dechex(ord($str{$i})+$nk[$k]).'.';
$k = ($k=32) ? 0 : $k++;
}
$out = substr($out,0,-1);
break;
case 1: //解密
$str = explode('.',$str);
$slen = count($str);
for($i=0;$i<$slen;$i++)
{
if(!$str[$i]) continue;
$out .= chr(hexdec($str[$i])-$nk[$k]);
$k = ($k=32) ? 0 : $k++;
}
break;
}
return $out;
}
?>
测试：
<?php
$key = '====Test Key! 测试秘史====这边随便填=====爱填啥填啥';
$str = 'http://www.phpx.com/happy/viewthread.php?tid=138779&pid=947632&page=1&extra=page%3D1#pid947632 ==>加个中文测试看看！再来变态符号!@#$%^&*()_+~=-":|?><《》？+——）（*&……%￥#@！~';
echo '<xmp>'.$estr = mykey($str,$key);
echo "rnrn";
echo mykey($estr,$key,1).'</xmp>';
?>
结果：
