In Zend 2 There are <ol> <li>Global configuration file &</li> <li>Module level configuration file</li> </ol> IF you want to know there use you can refer the link below <a href="http://zf2.readthedocs.org/en/latest/tutorials/config.advanced.html" rel="nofollow">How does configuration works in ZF2 </a> When I had a same scenario I used the above link to understand and exploit Zend Config module which is really good to handle the situation like this . create two files production.php local.php in both these files return this array based on the environment <pre><code>return array( "dbname" => "yourdbname" "dbhostname" => "dbhostname" "dbusername" => "yourdbusername", "dbpassword" => "yourdbpassword" ); </code></pre> in config/autoload/ directory of your zend framewrok application later edit your config/application.config.php file as per below instructions // get the application env from Apache vhost file ( here you can set in your apache vhost file as production or local ) <pre><code>$applicationEnv = getenv('APPLICATION_ENV'); </code></pre> $environmentSpecificConfigPath = "config/autoload/{,*.}{".$applicationEnv.",local}.php"; // Next with in the config array pass the environment specific configuration path <pre><code> 'config_glob_paths' => array($environmentSpecificConfigPath) </code></pre> in any controller or action you can just use the below code <pre><code> $configArray = $this->getGlobalConfig(); </code></pre> Now $configarray has all your DB credentials to create a connection <pre><code>$adapter = new Zend\Db\Adapter\Adapter(array( 'driver' => 'Mysqli', 'database' => $configArray['dbname'], 'username' => $configArray['dbusername'], 'password' => $configArray['dbpassword'] )); </code></pre> If you use config array to connect the DB in your entire application you dont need to worry about environment changes just make sure you have an Apache APPLICATION_ENV entry in your vhost file you can do that by adding below line in your apache vhost file <pre><code> SetEnv APPLICATION_ENV "production" // in your production server SetEnv APPLICATION_ENV "local" // in your local </code></pre> Also Last but not least you can use the Zend Experts module ZeDB <a href="https://github.com/ZendExperts/ZeDb" rel="nofollow">https://github.com/ZendExperts/ZeDb</a> To manage your CRUD applications Hope the above steps may help you in creating the environment

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
