解釋用於從子文件夾運行CodeIgniter的htaccess代碼

Question

我從一個子目錄運行CodeIgniter，其中mydomain.com打開我的default_controller（目前是歡迎屏幕），這個片段似乎適用於此目的，當放在我的/root/.htaccess中時，但即使有引用它仍然是魔術對我來說。

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]

有人可以逐行解釋這個htaccess代碼片段嗎？ 我錯過了什么至關重要的嗎？ 這是在我的/ root文件夾中，它需要從URL中刪除index.php，所以我在/ root / app / build / www /子文件夾中沒有放置.htacces

我在代碼中寫了一些評論：

# 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]
