使用Zend_Db_Adapter_PDO_Mysql类连接到mysql数据库

Question

How to connect to mysql db correctly? In my application.ini file, I have put all the db details:

[master]
adapter = PDO_MYSQL
params.host = localhost
params.username = root
params.password = ''
params.dbname = accounts_db

I want to get these details and connect to my db.

Answer 1

Try this one its work

resources.db.adapter = PDO_MYSQL
resources.db.params.host = localhost
resources.db.params.username = root
resources.db.params.password = 
resources.db.params.dbname = accounts_db

In my site it will work perfectly

Answer 2

When it's the default mysql database adapter you can add the line at the bottom, in that case it will be auto. used in Zend_Db_Table objects etc.

resources.db.adapter="pdo_mysql"
resources.db.params.host="localhost"
resources.db.params.username="username"
resources.db.params.password="pass"
resources.db.params.dbname="dbname"                       
resources.db.isDefaultTableAdapter=true   

On the otherside you can fetch the adapter at any place with

Zend_Db_Table::getDefaultAdapter();

Good luck.

Zend Framework is not the easiest framework to start application development. My best advice is to start reading the quickstart documentation , especially chapters dealing with Zend_Application , Zend_Db , Zend_Layout and of course Zend_Controller .

To answer your question, adding database configuration to application.ini isn't setting up the db connection. You should bootstrap an application resource using:

[production]

; Database (production)
resources.db.adapter = "pdo_mysql"
resources.db.params.host = "localhost"
resources.db.params.username = "my_user_who_is_not_root"
resources.db.params.password = "my_strong_password"
resources.db.params.dbname = "accounts_db"
resources.db.isDefaultTableAdapter = true

; Other configurations
; ...

[development : production]

; Database (development settings)
resources.db.params.username = "root"
resources.db.params.password = ""
resources.db.params.dbname = "accounts_db_dev"

At this point, your database connection is ready to query the server .

Into your controllers (or anything else), you can retrieve the connection using:

Zend_Db_Table::getDefaultAdapter();

You could also within your Bootstrap add a reference to the connection to the Zend_Register :

protected function _initDbRegister()
{
    $db = $this->bootstrap('Db')->getResource('Db');
    Zend_Register::set('Zend_Db', $db);
}

Later, you could call Zend_Register::get('Zend_Db') to get the instance.
