解釋用於從子文件夾運行CodeIgniter的htaccess代碼

Question

我從子目錄運行CodeIgniter，其中mydomain.com打開我的default_controller（當前是歡迎屏幕），並且此代碼段似乎適用於此目的，當放置在我的/ root/.htaccess，但即使引用它仍然對我來說很神奇。

Options +FollowSymLinks 
RewriteEngine On 
RewriteBase /app/main/build/www 

RewriteRule ^$ index.php [L] 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond $1 !^(index\.php|robots\.txt|favicon\.ico) 

RewriteRule ^(.*)$ index.php?/$1 [L] 

有人可以解釋這個htaccess的代碼段在低級行？我錯過了任何重要的東西？這是在我的/根文件夾，它需要擺脫index.php出url，所以我沒有在我的/ root/app/build/www /子文件夾沒有放置.htacces

我寫了一些評論在代碼：

# Tell the server to follow symbolic links 
Options +FollowSymLinks 

# Enable mod-rewrite 
RewriteEngine On 

# Strip /app/main/build/www from the string to be tested by regex 
RewriteBase /app/main/build/www 

# If the url empty, redirect to index.php (^ is start of line, $ is end of line) 
RewriteRule ^$ index.php [L] 

# If the url is not an existing directory 
RewriteCond %{REQUEST_FILENAME} !-d 
# And if the url is not an existing fie 
RewriteCond %{REQUEST_FILENAME} !-f 
# And if the file does not start with index.php or the other two... 
RewriteCond $1 !^(index\.php|robots\.txt|favicon\.ico) 
# Then rewrite the url to index.php?file, and make this the last rule 
# Note that (.*) captures every character of the file name to Group 1, and that 
# $1 is a reference to that capture (used once in the cond, once in the rule) 
RewriteRule ^(.*)$ index.php?/$1 [L]
