几个定义的常量(PATH结尾的常量表示目录路径,DIR结尾的变量表示目录名):
a. SELF(这里指index.php文件)
b. EXT(deprecated,废弃的,不必关注)
c. BASEPATH(system文件夹的路径)
d. FCPATH(前端控制器的路径)
e. SYSDIR(系统system目录名)
f. APPPATH(应用程序路径)
查看所有定义的常量的方法:
Print_r(get_defined_constants());
(2)application的目录验证。
代码较简单,不做过多的解释:
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.'/');
}
<?php
define('ENVIRONMENT', 'development');
if (defined('ENVIRONMENT'))
{
switch (ENVIRONMENT)
{
case 'development':
error_reporting(E_ALL);
break;
case 'testing':
case 'production':
error_reporting(0);
break;
default:
exit('The application environment is not set correctly.');
}
}
