using args[] to tell which server? - richb201 - 09-13-2018
I want to run my app either on the remote server or my localhost. To start it on my localhost I start the Apache and then type localhost in the browser window. To start it on the server I type 54.152.xxx.9/sub_crud on the browser address bar. In my database.cfg I have
if ($_SERVER['DOCUMENT_ROOT']="localhost") {
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => 'xxxx',
'database' => 'substantiator',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
}
else {
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => 'xxxx',
'database' => 'substantiator',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
I also have this in my config.cfg
if ($args[0]="localhost") {
$config['base_url'] = 'http://localhost//';
} else {
$config['base_url']='http://54.152.xxx.9/sub_crud/';
}
For some reason, the localhost database seems to always load. It also seems that DOCUMENT_ROOT is unreliable and seems to be set to localhost even though I am using the 54.152.xxx.9/sub_crud in the browser. Is there a better way to do this? The passwords for the databases on the two servers are different.

@richb201,
You could use the application environment feature of CI...
(setting environment variable) https://codeigniter.com/user_guide/general/environments.html?highlight=application%20environment#handling-multiple-environments
(setting config variables for specific environments) https://codeigniter.com/user_guide/libraries/config.html#environments
I use it for development and production environments which are on different servers.

That is a pretty cool thing. I realized that I should have used == instead of =, so I will try that first.
addendum:
I am going to try ENVIRONMENT since argc fails. One question, how do I set the ENVIRONMENT? I created a config/testing directory. In it I have a localhost centric config.php and database.php as the docs say to do. I then modified the index.php like this:
define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');
define ('ENVIRONMENT','testing');
and then I modified a few lines lower to:
switch (ENVIRONMENT)
{
case 'development':
case 'testing':
error_reporting(-1);
// ini_set("error_reporting", E_ALL & ~E_DEPRECATED); //rnb
ini_set('display_errors', 1);
break;
// case 'testing':
case 'production':
I thought that this would use development, but also use the config/testing config files. But it still uses the regular old config files, instead.

Got it working. I used this code in the index.php
$_SERVER['CI_ENV']='testing';
//define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');
define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');
