今天我们来深入的了解一下PHP语言的深层次概念。

特别说明:此PHP eval加密解密程序好像一定得在PHP5上面使用,

我在PHP4上面测试eval(gzinflate(base64_decode("codes")))内加密的代码始终无法正常解密

以下是PHP eval加密破解的代码:

?php
/*
Taken from http://www.php.net/manual/
de/function.eval.php#59862
Directions:
1. Save this snippet as decrypt.php
2. Save encoded PHP code in coded.txt
3. Create a blank file called decoded.txt
(from shell do CHMOD 0666 decoded.txt)
4. Execute this script (visit decrypt.php in
a web browser or do php decrypt.php in the shell)
5. Open decoded.txt, the PHP should be decrypted
if not post the code on http://www.ariadoss.

gzinflate执行PHP eval加密代码的解密方法翻译为中文后的文字
(此段汉字原始文件里面可没.嘿)
1. 把这整段脚本保存为decrypt.php
2. 把需要解密的代码保存为coded.txt并且和decrypt.php在同一目录.
3. 创建一个空白文件命名为 decoded.txt (必须把 decoded.
txt 的权限设置为CHMOD 0666,也就是可以写入的.当然,你可以
不创建文件文件.只要文件夹有写入权限,脚本便会自动创建一个
名为decoded.txt的文档. )
4. 运行PHP eval加密解密脚本 (浏览器中运行decrypt.php 即访问 http:
//您的域名/存放目录/decrypt.php)
5. 打开 decoded.txt, 代码应该已经解密完成，如果出现错误请
把代码发送到 http://www.ariadoss.com/forums/web-
