需要禁止某个目录运行程序，通过重写规则就能实现

apache的这样写,在重写规则中加入一行

 RewriteRule upload/(.*).(php)$ – [F]

<IfModule mod_rewrite.c>
 #RewriteEngine on
 #RewriteBase /
 #RewriteCond %{REQUEST_FILENAME} !-d
 #RewriteCond %{REQUEST_FILENAME} !-f
 #RewriteRule ^(.*)$ index.php?s=/$1 [QSA,PT,L]
 RewriteRule upload/(.*).(php)$ – [F]
</IfModule>

nginx的也可以在重写或配置文件中加入

location ~ /upload/.*.(php|php5)?$ {
deny all;
}
禁止单个目录

禁止多个目录这样写

location ~ /(upload|uploads)/.*.(php|php5)?$ {
deny all;
}
