Is it best practice to use Zend_Registry to make the DB adapter globally available in ZendFramework?

Using Zend_Registry to make the DB adapter globally available in Zend Framework is not considered a best practice. It is recommended to use Dependency Injection instead, as it promotes better code organization, testability, and flexibility. 

// Using Dependency Injection to pass the DB adapter to classes that need it
class SomeClass
{
    protected $dbAdapter;

    public function __construct(\Zend\Db\Adapter\Adapter $dbAdapter)
    {
        $this->dbAdapter = $dbAdapter;
    }

    public function someMethod()
    {
        // Use $this->dbAdapter to interact with the database
    }
}

// In your application bootstrap or configuration
$dbAdapter = new \Zend\Db\Adapter\Adapter($dbConfig);
$someClass = new SomeClass($dbAdapter);
