无法载入 mcrypt 扩展，<br />请检查 PHP 配置

windows下好解决,在php.ini里把相关的模块加载就可以了

在Linux,要以编译PHP里,加上相关选项

php config
--with-mcrypt[=DIR]     Include mcrypt support

在此之前,应该确认已安装 libmcrypt

可以在下面地址下载,手工编译安装
ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/

也可以用yum安装更方便

yum -y install libmcrypt
yum -y install libmcrypt-devel

如果没有安装,在编译PHP时,会提示如下
configure: error: mcrypt.h not found. Please reinstall libmcrypt.

wget http://x.x.x.47/eaccelerator-0.9.5.3.tar.bz2

export PHP_PREFIX="/opt/php"
$PHP_PREFIX/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=$PHP_PREFIX/bin/php-config
make
make install

Libraries have been installed in:
   /home/eaccelerator-0.9.5.3/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

上面是在网上看的,但用不了?程序也像很有问题.懒得理,还是自己修改下来用.

下面作了修改后的

$i=1;
$contents = gzinflate(str_rot13(base64_decode($s)));
while (preg_match("/eval[ ]*\([ ]*gzinflate/",$contents)) {//在eval(的'('两边加入多空格匹配    
echo '次数:'.$i++."\n";//显示解密次数
preg_match("/'(.*)'/isU",$contents,$s1);

$s2=$contents;
$contents = gzinflate(str_rot13(base64_decode($s1[1])));
} 
echo "结果:\n"; 
echo $s2;

有点郁闷,好像每过一段时间,就要和这些打下交道.而且,这次搞得也有水准了,加了这么多次密,但最终还是要显形的.

DEDE,总是能让人找到个洞,然后再上传点资料,呵呵

正则学习笔记

普通字符 如 a-zA-z0-9
特殊字符,亦称元字符 如 +^%$

基本语法 /string/

常用元字符 +,*,?
+ 连续一次或多次
* 连续零次或多次
? 连续零次或一次
如/fo+/,/eg*/,/wil?/

{}匹配频率
如/{jim{2,6}/,连续出现2-6次,如jimmy

几个重要的元字符的使用方式。
　　\s：用于匹配单个空格符，包括tab键和换行符；
　　\S：用于匹配除单个空格符之外的所有字符；
　　\d：用于匹配从0到9的数字；
　　\w：用于匹配字母，数字或下划线字符；
　　\W：用于匹配所有与\w不匹配的字符；
　　. ：用于匹配除换行符之外的所有字符。
　　（说明：我们可以把\s和\S以及\w和\W看作互为逆运算）
如
/\s+/ 一个或多个空格字符
/\d000/  千数

常用的定位符包括： “^”, “$”, “\b” 以及 “\B”。
^ 开头,如/^hell/,hello
$ 结尾,如/ar$/,car
\b 开头或结尾的两个边界之一,如/\bbom/ bomb,/man\b/ human
\B 开头和结尾两个边界之内
设定一个范围
/[a-z]/ 小写
/[A-Z]/ 大写
/[0-9]/ 数字
/([a-z][A-Z][0-9]+/ 如aB0

运算符
管道符(或运算)"|"
如/to|too|2/ 与to,too,2相匹配

否定符(非) "[^]"
如 /[^A-C]/ 除ABC外的任意字符
一般来说，当“^”出现在 “[]”内时就被视做否定运算符；而当“^”位于“[]”之外，或没有“[]”时，则应当被视做定位符。

转义字符"\"
如:/Th\*/,匹配Th*

Linux下

在编译PHP时加上参数 --with-curl,即可.如果是在用的环境,则重新编译PHP

windows

1、拷贝PHP目录中的libeay32.dll 和 ssleay32.dll 两个文件到 system32 目录。
2、修改php.ini：配置好 extension_dir ，去掉 extension = php_curl.dll 前面的分号。

一个不错的PHP下各种编码转换类

 * 中文编码集合类库
 *
 * 目前该类库可以实现，简体中文 <-> 繁体中文编码互换，简体中文、繁体中文 -> 拼音单向转换，
 * 简体中文、繁体中文 <-> UTF8 编码转换，简体中文、繁体中文 -> Unicode单向转换
