multiple instances only config files change

Hello,
i try on google and did not find anything. sorry for my bad English.

i am working bussince application in CI 3. i had multiple clients with same application.
setup different instance but each client had own database and few config parameters on server.
my problem is when i am apply new patch i need to apply it on all instances most of time i forget to apply patch on some instance.


- application server is same.
- domain name different for each client. 
- i am thinking when users hit domain application load specific config folder.

it is possible to setup single application code and multiple config folder?

Can you supply typical details of "config file changes".


Do all applications share a single system folder?

yes all application and system folder is same, database name different in database.php and config variables in config.php

PHP Code:

date_default_timezone_set('xxx/xxx');
setlocale(LC_ALL, 'fil_PH');
$config['diler_prefix'] = 'tel:0';
$config['_login_site_name'] = "ASEAN"; 


i want to single project folder for patch/update code/changes apply on production and each client instance operate with different database config file variables .
i try google... but not lucky...

it possible to define config folder or only database.php,config.php path in index.php maybe it solve my problem.

I usually test for the server name and set $config values accordingly:

Code:

$_SERVER_NAME = $_SERVER['SERVER_NAME'];

switch($_SERVER_NAME ) :

case 'abc.com':
  date_default_timezone_set('xxx/xxx');
  setlocale(LC_ALL, 'fil_PH');
  $config['diler_prefix'] = 'tel:0123';
  $config['_login_site_name'] = "ASEAN-001";
break;

case 'xyz.com':
  date_default_timezone_set('xxx/xxx');
  setlocale(LC_ALL, 'fil_PH');
  $config['diler_prefix'] = 'tel:0456';
  $config['_login_site_name'] = "ASEAN-009";
break;

case 'locahost':
default:
  date_default_timezone_set('xxx/xxx');
  setlocale(LC_ALL, 'fil_PH');
  $config['diler_prefix'] = 'tel:0456';
  $config['_login_site_name'] = "ASEAN-009";
break;
endswitch;

There are lots of other $_SERVER variables abvaliable:

Code:

echo '<pre>'; // add line feeds
  print_r( $_SERVER);
  die;

Personally I'm using application environment variables from Apache/Nginx.

PHP Code:

/*
 *---------------------------------------------------------------
 * APPLICATION ENVIRONMENT FROM APACHE/NGINX
 *---------------------------------------------------------------
 *
 * Apache: SetEnv VARNAME myvariable
 * Nginx:  fastcgi_param VARNAME myvariable;
 *
 * Required
 * CI_DB_HOSTNAME
 * CI_DB_USERNAME
 * CI_DB_PASSWORD
 * CI_DB_DATABASE
 * CI_BASE_URL
 *
 * Optional
 * CI_BASE_PATH
 * CI_CDN_URL
 * CI_PROGRAM_NAME
 * CI_PROGRAM_DESC
 * CI_PROGRAM_DESC_SHORT
 * CI_SESS_SAVE_PATH
 *
 */ 


In the same way CodeIgniter grabs it's environment variable.

PHP Code:

/*
 *---------------------------------------------------------------
 * APPLICATION ENVIRONMENT
 *---------------------------------------------------------------
 *
 * You can load different configurations depending on your
 * current environment. Setting the environment also influences
 * things like logging and error reporting.
 *
 * This can be set to anything, but default usage is:
 *
 *     development
 *     testing
 *     production
 *
 * NOTE: If you change these, also change the error_reporting() code below
 */
    define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'production'); 


That means you don't need to update your project at all. Everything are done from Apache / Nginx configuration instead.

Thank you . and how to handle database  ?

Same idea, check and set the SERVER_NAME and use the values in ./app/Config/Database.php
