Hi, I was having problems each time I had to test the site or edit something on my local machine, like changing the db connection, change the debug mode to false, the trace level to 0, disable Gii, etc. So I created a class to resolve all my problems, hope to help you in your projects!
Instructions ¶
- Configuring the Easy Environment class
- Configuring your index.php file
- Changing your environment
- Get your actual environment
Configuring the Easy Environment class ¶
Create a new file in the config folder, name it 'environment.php'.
Paste the following code in your 'environment.php' file.
/**

}// END Environment Class
- Change the configuration for each environment:
- DEVELOPMENT
- TEST
- STAGE
- PRODUCTION
Configuring your index.php file ¶
- Open your index.php file an replace all the code with the following code:*
// Change the following paths if necessary
require_once(dirname(__FILE__).'/protected/config/environment.php');
$environment = new Environment(Environment::DEVELOPMENT) ;
$yii = dirname(__FILE__).'/../../framework/yii.php';
defined('YII_DEBUG') or define('YII_DEBUG',$environment->getDebug());
defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL', $environment->getTraceLevel());
require_once($yii);
Yii::createWebApplication($environment->getConfig())->run();
Changing your environment ¶
- To change the environment just you have to change the following code:
//For development
$environment = new Environment(Environment::DEVELOPMENT);
//For test
$environment = new Environment(Environment::TEST);
//For stage
$environment = new Environment(Environment::STAGE);
//For production
$environment = new Environment(Environment::PRODUCTION);
Get your actual environment ¶
- You can check inside your application in what environment you are working with the following code:
// This will return the environment code number
$currentEnvironment = Yii::app()->getParams()->environment;
// Compare if the current environment is lower than production
if($currentEnvironment < Environment::PRODUCTION){
//Your code here...
}else{
//Your code here...
}
Enjoy it! ;D
Solution with complete config seperation (addition)
To use my solution with testing, modify your protected/tests/bootstrap.php like this:
<?php $yiit=dirname(__FILE__).'/../../../yii/framework/yiit.php'; // set environment require_once(dirname(__FILE__) . '/../../protected/config/Environment.php'); $env = new Environment('TEST'); //override // run Yii app require_once($yiit); require_once(dirname(__FILE__).'/WebTestCase.php'); Yii::createWebApplication($env->getConfig())->run();Solution with complete config seperation (note)
Merging config arrays is not working as I expected when both arrays have a certain value. Yii is using CMAP::mergeArray to do this properly. To fix this, you can use:
// Merge config arrays into one //$this->_config = array_merge_recursive($config, $configSpecific); require_once(dirname($yiiPath). DIRECTORY_SEPARATOR . 'base' . DIRECTORY_SEPARATOR . 'CComponent.php'); require_once(dirname($yiiPath). DIRECTORY_SEPARATOR . 'collections' . DIRECTORY_SEPARATOR . 'CMap.php'); $this->_config = CMap::mergeArray($config, $configSpecific);I will see about working out a solution where the config files don't have to be merged up front, to keep from including Yii files before the webapp is created.
Solution with complete config seperation
Based on the versions from authors above, I created my own version of this script.
There is no environment specific code in the Environment.php class, everything is seperated into the config files.
Impact on changing the index.php is minimal, but the configuration files need some slight modifications to incorporate the extra attributes. I might also turn them into classes at some point.
Environment is determined by Apache's SetEnv, but this can be easily changed at Environment::getMode()
Here is the code.
protected/config/Environment.php
<?php /** * Simple class used to set configuration and debugging depending on environment. * This allows for a custom Yii path, debugging vars, and config array. * * Environment is determined by $_SERVER[YII_ENVIRONMENT], created * by Apache's SetEnv directive * This can be done in the httpd.conf or in a .htaccess file for ease of use. * See: http://httpd.apache.org/docs/1.3/mod/mod_env.html#setenv * ******************************************************************************* * * Index.php usage example: * * // set environment * require_once(dirname(__FILE__) .

It's a great class, but I prefer to see the passwords in separated files.

The usage is the same as nancoder class, in index.php
require_once(dirname(__FILE__).'/protected/config/environment.php'); $environment = new Environment() ; defined('YII_DEBUG') or define( 'YII_DEBUG' , $environment->debug ); defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL', $environment->traceLevel ); $environment->processRequire(); Yii::createWebApplication( $environment->config )->run();Excellent idea
I really like this class. Great idea!
You could (if desirable) automate it a little further by letting the application set its own environment dynamically based on the application's path.
For instance, I have my application installed in a certain path like '/home/me/sites/my_application' on my development machine, and something like '/var/apps/live_application' on my production box, so you could use something like this in your index.php file:
$env = ( stristr( dirname(__FILE__), '/home/me' ) ? new Environment(Environment::DEVELOPMENT) : new Environment(Environment::PRODUCTION);Bug show $this->getDebug()
i get hard to show Bug show $this->getDebug() in param config.
and its solved by relocate $this->_config = array_merge_recursive ($this->_main(), $this->_development()); before break;
and will like this;
private function setConfig() {
switch($this->_mode)
{ case self::DEVELOPMENT: $this->_debug = true; $this->_trace_level = 3; $this->_config = array_merge_recursive($this->_main(),$this->_development()); break; case self::TEST: $this->_debug = false; $this->_trace_level = 0; $this->_config = array_merge_recursive($this->_main(),$this->_test()); break; case self::STAGE: $this->_debug = true; $this->_trace_level = 0; $this->_config = array_merge_recursive($this->_main(),$this->_stage()); break; case self::PRODUCTION: $this->_debug = false; $this->_trace_level = 0; $this->_config = array_merge_recursive($this->_main(),$this->_production()); break; default: $this->_debug = true; $this->_trace_level = 0; $this->_config = $this->_main(); break; } }its worked
