上传到服务器的codeigniter项目给我以下错误.

Your system folder path does not appear to be set correctly. Please

open the following file and correct this: index.php

它在当地运作良好在000webhost.com托管.

When uploaded to private server of parallels it gives the above error.

我的index.php如下.

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.');

}

}

$system_path = 'system';

$application_folder = 'application';

if (defined('STDIN'))

{

chdir(dirname(__FILE__));

}

if (realpath($system_path) !== FALSE)

{

$system_path = realpath($system_path).'/';

}

$system_path = rtrim($system_path, '/').'/';

if ( ! is_dir($system_path))

{

exit("Your system folder path does not appear to be set correctly. Please open the following file and correct this: ".pathinfo(__FILE__, PATHINFO_BASENAME));

}

define('SELF', pathinfo(__FILE__, PATHINFO_BASENAME));

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.'/');

}

require_once BASEPATH.'core/CodeIgniter.php';
