Access to database zend framework

问题

I want to access to database "mysql", I read that we can define the db adapter and db configurations by writing these lines in application.ini file

resources.db.adapter = MYSQLI
resources.db.params.host = localhost
resources.db.params.username = root
resources.db.params.password =123456
resources.db.params.dbname = visits_db

I want to get the $db object in order to use in for executing sql statements

    $db->insert("inspection_visits_tb",
            $insepctionVisitData = array(
        'day' => $visit->getDay(),
        'date' => $visit->getDate(),
        'target' => $visit->getTarget()
    ));

I want to get it from the application.ini file not like this

require_once 'Zend/Db.php';
    $db = Zend_Db::factory("MYSQLI",
                    array(
                        "host" => "localhost",
                        "dbname" => "visits_db",
                        "username" => "root",
                        "password" => "123456")
    );

because I want to define the db adapter in one place only. What should I do to get the $db object??

回答1:

Set up the db resource in application.ini like you were. Add the isDefaultAdapter option.

resources.db.adapter = "MYSQLI"
resources.db.params.host = "localhost"
resources.db.params.username = "root"
resources.db.params.password = "123456"
resources.db.params.dbname = "visits_db"
resources.db.isDefaultAdapter = true

Then to get the $db object...

In Bootstrap.php

protected function _initDb()
{
    $this->bootstrap('db');
    $db = $this->getResource('db');
    Zend_Registry::set('db', $db);
}

From Somewhere else w/out using Registry

$db = Zend_Db_Table::getDefaultAdapter();

Using Zend_Db_Table

$table  = new Zend_Db_Table('bugs');
$select = $table->select()...

See also ZF Quickstart, Zend_Db_Table, Zend_Db_Select for more examples.
