我偶然发现了这个页面
https://www.codeigniter.com/user_guide/general/reserved_names.html
谁能给我解释一下下列常量的作用:
EXT
FCPATH
SELF
BASEPATH
APPPATH
谢谢
这些常量分别在index.php
页面中定义:
/*
* -------------------------------------------------------------------
* Now that we know the path, set the main path constants
* -------------------------------------------------------------------
*/
// The name of THIS file
define('SELF', pathinfo(__FILE__, PATHINFO_BASENAME));
// The PHP file extension
// this global constant is deprecated.
define('EXT', '.php');
// Path to the system folder
define('BASEPATH', str_replace("''", "/", $system_path));
// Path to the front controller (this file)
define('FCPATH', str_replace(SELF, '', __FILE__));
// Name of the "system folder"
define('SYSDIR', trim(strrchr(trim(BASEPATH, '/'), '/'), '/'));
// The path to the "application" folder
if (is_dir($application_folder))
{
define('APPPATH', $application_folder.'/');
}
else
{
if ( ! is_dir(BASEPATH.$application_folder.'/'))
{
exit("Your application folder path does not appear to be set correctly. Please open the following file and correct this: ".SELF);
}
define('APPPATH', BASEPATH.$application_folder.'/');
}
从https://github.com/EllisLab/CodeIgniter/blob/develop/index.php第196行开始
您可以在CI文件夹根目录下的index.php中找到它的简短定义。
EXT: The PHP file extension
FCPATH: Path to the front controller (this file) (root of CI)
SELF: The name of THIS file (index.php)
BASEPATH: Path to the system folder
APPPATH: The path to the "application" folder
自我 = index . php
当您想包含根文件夹中的内容时使用
FCPATH = C: ' xampp '根' your_root_folder '
当您想包含应用程序文件夹中的内容时使用
APPPATH = C:'xampp'htdocs'your_root_folder'application'
BASEPATH = C: ' xampp '根' your_root_folder ' system '
