Zend Framework2 Another way to implement multi-database configuration

Compared to the first one I ever made in Zend Framework2 to implement multi-database configuration use: http://blog.csdn.net/a437629292/article/details/41121455; I prefer this method!

Don't worry, listen to me slowly.

1. Problem: The first method (see above connection), is not to instantiate a model, all to instantiate a database adapter, this is not a bit of a waste of resources?

So, I have been dissatisfied with this implementation, has been looking for how to be able to a request (regardless of the number of model calls), even from the start of the project, only the database adapter is instantiated once.

2. Idea: Pubilc/index.php is the only entry file, which means that all requests need to go through index.php, then there is a little inspiration, is not I in the index.php to instantiate a database adapter array,

Then according to the configuration or parameters, to choose which database adapter to instantiate?

3. Practice: Now that you have this idea, hurry to practice one:

Add the following code to the index.php:

Instantiate all the database adapters $configs=new Zend_config_ini (Application_path. ' /configs/serverconfig.ini '); $dbAdapters = Array ();//$configArray = Array (); $registry =zend_registry::getinstance (); foreach ($configs as $config) {$databaseName = $config->db->params->dbname; $registry =zend_registry:: GetInstance (); $configArray [$databaseName] = $config; $registry->set (' Configarray ', $configArray);//Configuration Database $db= Zend_db::factory ($config->db); Instantiate an appropriate database adapter $db->query ("Set names UTF8"), $dbAdapters [$databaseName] = $db; $dbAdapters [$databaseName] = Zend_ Db::factory ($config->db->adapter, $config->db->params->toarray ()); if ($config->db->params- >default) = = 1) {zend_db_table::setdefaultadapter ($DB);}} $registry->set (' dbadapters ', $dbAdapters);

In this way, all the metabase nodes in the Serverconfig.ini are instantiated into the database adapter and loaded into the array, which we can use.

What I do now is to set the default database adapter, and the code in Serverconfig.ini is as follows:

[Promanager]db.adapter = PDO_MYSQLdb.params.host = 127.0.0.1:3306db.params.username = Rootdb.params.password = Rootdb.params.dbname = ProManagerdb.params.default = 0[promanager1]db.adapter = PDO_MYSQLdb.params.host = 127.0.0.1:3306db.params.username = Rootdb.params.password = Rootdb.params.dbname = ProManager1db.params.default = 1

In this way, you can easily implement the database by setting the default parameter instead of using it! OY ...
