Remove index.php in the URL for Codeigniter:

Options -Indexes

<IfModule mod_rewrite.c>

    RewriteEngine on
    RewriteBase /selfcontrol/

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d 

    #Uncomment one of the following rewrite rules. 
    #Some servers require the ? after index.php, some don't

    #RewriteRule ^(.*)$ index.php?/$1 [NC,L,QSA]
    RewriteRule ^(.*)$ index.php/$1 [NC,L,QSA]

</IfModule>

<IfModule !mod_rewrite.c>
    ErrorDocument 404 index.php
</IfModule>

1. FTP在传送文件时分为ASC和Bin两种格式，只有文字文件(例如 html 文件)使用ASC，其他的通通使用Bin格式(例如图像文件、压缩文件、可执行文件等等)。
2. 当我们使用ftp时，可简单地把文件分为两种基本类型：文本文件和二进制文件；文本文件也称为ASCII文件，其文件内容遵循ASCII的定义，其主要特征是文件内容由若干行组成，可以使用操作系统的显示、编辑命令来显示和编辑ASCII文件的内容，它使用的传输模式是asc；二进制文件（Binary File）是指除ASCII文件以外的所有文件格式，它使用的传输模式是bin；需要注意的是，可以将ASCII文件按二进制模式传输，但决不能将二进制文件按ASCII模式传输，否则二进制文件的内容会遭到破坏而无法使用。
3. ASCII 切换传输模式为文字模式（只能用来传送文字文件）； BINARY 切换传输模式为二进制模式（除文字文件外皆用此模式）；
4. 文字文件传输推荐ASC而程序或数据文件必须使用BIN。

.htaccess要用ASCII传。

I was using Codeigniter with Backbone. When I try to call the save() method in the Backbone it sent a POST Request to the server. But it sends data to the server using a Request Payload and not the standard Form Data approach that jQuery, and standard HTML forms submit with.. After a bit study I think there are two easy way to handle this.

On the front end you can enable Backbone.emulateJSON() or on the server side, $requestBody = json_decode(file_get_contents('php://input'),true);.

I heard something like $this->request->body but it never works.

One .htaccess File

Regular expressions

• ^ begins the line to match.
• $ ends the line to match. So, ^folder1$ matches folder1 exactly.
• . stands for “any non-whitespace character” (example: a, B, 3).
• * means that the previous character can be matched zero or more times. So, ^uploads.*$ matches uploads2009, uploads2010, etc.
• ^.*$ means “match anything and everything.” This is useful if you don’t know what your users might type for the URL.
• () designates which portion to preserve for use again in the $1 variable in the second string. This is useful for handling requests for particular files that should be the same in the old and new versions of the URL.
