mysql - Zend Framework: Select query -

i'm newbie on zend framework, created dbtable , primary key id , , table name user:

<?php  class application_model_dbtable_user extends zend_db_table_abstract {      protected $_name = 'user';     protected $_primary = 'id';  } 

after ,i reviewed abstract.php(db/table/abstract.php) , found out had use insert(array $data), created model: (register.php)

<?php  class application_model_register {     public function createuser($array)     {         $dbtableuser = new application_model_dbtable_user();         $dbtableuser -> insert($array);     }  } 

and , in controllers , created indexcontroller.php

<?php class indexcontroller extends zend_controller_action {     public function init()     {         /* initialize action controller here */     }      public function indexaction()     {         $register = new application_model_register();         $register-> createuser(array(                'username'=>'test'));     } } 

it works correctly , have no idea select, how select query user table?

our controller should have below

<?php class indexcontroller extends zend_controller_action {     public function getdataaction()     {          $register = new application_model_dbtable_register();          $register->getlistofuser();      } } 

now model should have this,

<?php  class application_model_dbtable_register extends zend_db_table_abstract {      protected $_name = 'user';     protected $_primary = 'id';       public function getlistofuser()     {          $db = zend_db_table_abstract::getdefaultadapter();         $select  = $db->select()                       ->from($_name,array('*'))                       ->where(1);         $data = $db->query($select)->fetchall();         return $data;              } }
