screw plus是一个开源的php扩展，作用是对php文件进行加密，网络上提供php加密的服务很多，但大多都只是混淆级别的加密，被人拿到加密文件问只要有足够耐心就能破解，与之不同的是，screw plus采用扩展来加解密，而且是全球金融业流行的高强度AES256加密，除非破解了服务器，否则黑客拿到了加密文件也只是一堆乱码。
同一个加密级别的有ioncube和官方的zend guard，但这两款都是收费的，一年至少数千元的费用并不值得普通开发者去尝试，而使用screw plus，你不需要多花一分钱。
下面以LNMP一键安装环境为例演示下screw plus的配置
首先克隆一份代码到服务器
git clone https://git.oschina.net/splot/php-screw-plus.git
进入项目目录，然后执行php的phpize文件，phpize是官方提供的可执行文件用于动态生成扩展开发环境，一般在php的bin目录下可以找到。lnmp的phpize
# /usr/local/phpphpize
Cannot find config.m4.
Make sure that you run '/usr/local/php/bin/phpize' in the top level source directory of the module
在
# cd /usr/local/src/lnmp-install-pakge/php-7.0.27/ext下找到工具
# ./ext_skel --extname=my_module
Creating directory my_module
Creating basic files: config.m4 config.w32 .gitignore my_module.c php_my_module.h CREDITS EXPERIMENTAL tests/001.phpt my_module.php [done].
To use your new extension, you will have to execute the following steps:
1. $ cd ..
2. $ vi ext/my_module/config.m4
3. $ ./buildconf
4. $ ./configure --[with|enable]-my_module
5. $ make
6. $ ./sapi/cli/php -f ext/my_module/my_module.php
7. $ vi ext/my_module/my_module.c
8. $ make
Repeat steps 3-6 until you are satisfied with ext/my_module/config.m4 and
step 6 confirms that your module is compiled into PHP. Then, start writing
code and repeat the last two steps as often as necessary.
执行了这个步骤以后你会看到这样的结果
Repeat steps 3-6 until you are satisfied with ext/my_module/config.m4 and step 6 confirms that your module is compiled into PHP. Then, start writing code and repeat the last two steps as often as necessary.
这样以后我们会在这个目录下生成一个目录叫my_module
进入这里面我们看看
# cd my_module/
# ls
config.m4 config.w32 CREDITS EXPERIMENTAL my_module.c my_module.php php_my_module.h tests
然后我们要修改文件顺序是
config.m4
my_module.c
php_my_module.h
# vim config.m4
将
dnl PHP_ARG_ENABLE(my_module, whether to enable my_module support,
dnl Make sure that the comment is aligned:
dnl [ --enable-my_module Enable my_module support])
修改成
PHP_ARG_ENABLE(my_module, whether to enable my_module support,
Make sure that the comment is aligned:
[ --enable-my_module Enable my_module support])
最后在该目录下运行
# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20151012
Zend Module Api No: 20151012
Zend Extension Api No: 320151012
编译配置
# ./configure --with-php-config=/usr/local/php/bin/php-config
编译时，发现少了个re2c
# wget https://nchc.dl.sourceforge.net/project/re2c/0.16/re2c-0.16.tar.gz
# tar -zxvf re2c-0.16.tar.gz
# cd re2c-0.16/
# ./configure && make && make install
完成编译安装
# make(
./configure --with-php-config=/usr/local/php/bin/php-config)

Libraries have been installed in:
/usr/local/src/lnmp-install-pakge/php-7.0.27/ext/my_module/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.

Build complete.
Don't forget to run 'make test'.

Do you want to send this report now? [Yns]:
进入tools
# cd tools
# make
把生成的 my_module.so复制到扩展目录下
# cp my_module.so /usr/local/src/lnmp-install-pakge/php-7.0.27/ext
进入php.ini
# vim /usr/local/php/lib/php.ini
添加
extension=/usr/local/src/lnmp-install-pakge/php-7.0.27/ext/my_module.so
然后重启php服务 这时可以放个php文件输出phpinfo信息，如果看到以下提示说明扩展生效了
在扩展的tools目录，执行./screw [路径]，[路径]可以是单个文件也可以是文件夹，然后就可以实现加密了。
/screw [PATH] -d 解密代码
