I have my own mysql_connect ...etc until i wanted to use ZEND framework in particular with Zend_DB .How do I pass my connection to be used as an adapter to ZEND?
$myconn = mysql_connect('...blab',blah etc...)
eg. Zend_DB_table::setAdapter($myconn);
Don't connect to DB on your own, rather use the factory
$db = Zend_Db::factory('Pdo_Mysql', array(
'host' => '127.0.0.1',
'username' => 'webuser',
'password' => 'xxxxxxxx',
'dbname' => 'test'
));
This way you can connect to DB, but it will connect only once you need the connection and thus optimize for performance...

I am new into yii. I was transferring a premade yii website to my aws server. After adding the updated database info into protected/config/main.php I am getting this error. None of the references worked. Please help.

Possible Issue:
1) PDO driver maybe its not enabled
2) your dsn connection not truth, make sure your configuration somthing like this:
return [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=localhost;dbname=dbName',
'username' => 'root',
'password' => 'yourPAssword',
'charset' => 'utf8',
];
Note: make sure mysql: is set in dsn.
3) make sure your mysql port is 3306, if other one try to change dsn by adding port like this 'dsn' => 'mysql:host=localhost;port=portNumber;dbname=dbName',.
Good Luck
In CakePHP 3.0, what's the equivalent of calling getDataSource() from inside a controller (like $this->ModelName->getDataSource()in cakephp 2.x)?
I have tried this:
use Cake\Datasource\ConnectionManager;
$conn = ConnectionManager::get('my_connection');
Since this connection is connected already, why do I need to provide 'my_connection'?
How can I can get the DataSource from inside a Controller in CakePHP 3.0?
Thanks
Database\ConnectionManager::get() has been added. It replaces getDataSource()
CakePHP Cookbook 3
Begin, commit and rollback are now functions on the connection, not the data source. Use $conn = ConnectionManager::get($connectionName) and then use $conn->begin(), $conn->commit() and $conn->rollback().
http://book.cakephp.org/3.0/en/orm/database-basics.html#using-transactions
And use $this->Table->defaultConnectionName() to get the connection name to pass to get.
"my_connection" should be defined in cakephp 3 config
.go to cakephp/config/app.php
'Datasources' => [
'default' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'localhost',
/**
* CakePHP will use the default DB port based on the driver selected
* MySQL on MAMP uses port 8889, MAMP users will want to uncomment
* the following line and set the port accordingly
*/
//'port' => 'non_standard_port_number',
'username' => 'root',
'password' => '',
'database' => 'cake',
'encoding' => 'utf8',
'timezone' => 'UTC',
'flags' => [],
'cacheMetadata' => true,
'log' => false,
connection name is "default" for this case.
Each Model that used in controller have one Connection.
You can get connection in controller from model by this method.
$model=TableRegistry::get('table_name');
$connection = $model->connection();
Can I check if a mysql connection can be established with the given credentials from the controller?(i.e. host, username, pwd etc.)
Please note that I am not talking about setting my rails database.
I have a create form which returns some database credentials and I need to check if such connection exists before storing it in my database.
Thanks in advance
You could use the mysql2 module, then trying to open a new connection:
require 'mysql2'
conn = Mysql2::Client.new(:host => 'localhost', :username => 'user', :password => 'password', :port => '1111', :database => 'database_name')

Database connection error in Yii
(2 answers)
Closed 9 years ago.
I've got a new domain & hosting but I can't connect to the new db.
What I tried:
'db'=>array(
'connectionString' => 'mysql:host=ascodcurro.com.mysql;dbname=ascodcurro_com',
'emulatePrepare' => true,
'username' => 'ascodcurro_com',
'password' => 'xxxx',
'charset' => 'utf8',
),
If I try localhost as always it works fine.
User info from host:
MySQL
server: ascodcurro.com.mysql
DB: ascodcurro_com
user: ascodcurro_com
pw: *****
PhpMyAdmin
PhpMyAdmin: https://dbadmin.one.com/
user: ascodcurro_com
pw: ******
During the initial startup and working with Yii, the first problem that I faced was connecting to the database.
I was getting a really weird error and I was not able to connect to my DB on my Mac OSX Mountain Lion on my XAMPP stack. After countless searches, I finally figured out a method that worked. This is the only way I am able to connect to my DB for Yii.
First check if you can connect to the database normally using the
default configuration by uncommenting the 'db' configuration in the
main.php file. Example :
'db'=>array(
'connectionString' => 'mysql:host=localhost;dbname=ascodcurro_com',
'emulatePrepare' => true,
'username' => 'username',
'password' => 'pass',
'charset' => 'utf8',
'tablePrefix'=>'',
'enableProfiling'=>true,
'enableParamLogging'=>true,
),
However, if you are still not able to connect to the database even after this, as I wasn't able to connect to mine, try taking this approach :
Make a new php file and type :
<?php phpinfo() ?>
check that page out, find out where 'mysql' is located and find out the 'MYSQL_SOCKET' in it and note the location.
After noting the location down, try this as your 'db' connection string(for example, for me the location is "/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock") :
'connectionString' => 'mysql:unix_socket=/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock;dbname=practice',
And the rest as the basic parameters that you use.
And then try connecting again.
Hopefully, that should connect you to your DB.
Regards,
'db'=>array(
'connectionString' => 'mysql:host=localhost;dbname=basename',
'emulatePrepare' => true,
'username' => 'username',
'password' => 'pass',
'charset' => 'utf8',
'tablePrefix'=>'',
'enableProfiling'=>true,
'enableParamLogging'=>true,
),
its my config. You get any errors?
I have my Cake app and it's is working on my PC on Apache but it connects to the remote database.
And everything is fine.
But when I copied my app on server, there is an error when I try to execute any controller:
Error: SQLSTATE[HY000] [2005] Unknown MySQL server host 'xx.xx.xx.xx:33306' (2) requires a database connection
Error: Confirm you have created the file : app/Config/database.php.
And I tested the connection in simple php script (on server) and I connect and get data from this database without problem. So why Cake can't connect to it?? What might be problem?
public $external = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'xx.xx.xx.xx:33306',
'login' => 'xxx',
'password' => 'xxx',
'database' => 'xxx',
);
The file 'database.php' exists in app/config and has permissions rwxr-xr-x
I am not sure about mod_rewrite... how I can check it?
'host' => 'xx.xx.xx.xx:33306',
is not allowed. You should use the optional port option as specified in the CakePHP docs.
public $external = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'xx.xx.xx.xx',
'port' => '33306',
'login' => 'xxx',
'password' => 'xxx',
'database' => 'xxx',
);
