PHP禁用EVAL的错误理解

# cd /usr/local/src

重启apachectl,查看phpinfo信息，会出现

等许多Suhosin信息那么你就成功了。呵呵。
在这里也顺便说一下将suhosin安装成为php的动态扩展的方法。
wget http://download.suhosin.org/suhosin-0.9.23.tgz
tar zxvfsuhosin-0.9.23.tgz
cd suhosin-0.9.23
/usr/local/php/bin/phpize //这一步不能省
./configure --with-php-config=/usr/local/php/bin/php-config //必须在这儿注明php-config所在的绝对路径。
make
make install
会提示编译的模块存在的目录，记住它。
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/
然后在php.ini中增加一行下列语句。
extension=suhosin.so
suhosin.executor.disable_eval = on

suhosin.executor.disable_eval = on
[PATH=/htdocs/www/ex1/]
suhosin.executor.disable_eval = off
