Unable to import DataSource class due to incompatible driver for the cake version used
please suggest a compatible mysql connection driver for cakephp 1.3 on docker
CakePHP 1.3 didn't use namespaces. I think you just want 'driver' => 'mysql'.

I am trying to connect mysql to zend framework 3 application but it gives such result as below:
Class 'Zend\Db\Adapter\Adapter\Driver\Mysqli' not found
I am using below code:
$config = [
'driver' => 'Mysqli',
'database' => 'abc',
'host' => 'localhost',
// 'port' => 27017,
'username' => 'root',
'password' => '',
];
$adapter = new Mysqli($config);
$result = $adapter->query("select * from
table1",Adapter::QUERY_MODE_EXECUTE);
foreach($result as $row){
echo $row->sentence;"<br>";
}
inserted this as well. use Zend\Db\Adapter\Adapter\Driver\Mysqli;
I can see how to have multiple connections using a configuration file in app/config/database.php and this is well documented.
Is this the only way or can you also define multiple connections using the .env file?
First, you'll need to configure your connections. You need to create a config directory in your project and add the file config/database.php. Like this:
<?php
return [
'default' => 'mysql',
'connections' => [
'mysql' => [
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'homestead',
'username' => 'root',
'password' => 'secret',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
'mysql2' => [
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'homestead2',
'username' => 'root',
'password' => 'secret',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
],
Once you've added your connection configurations, you can access them by getting the database manager object out of the container and calling ->connection('connection_name'). See below for a full example.
<?php
namespace App\Http\Controllers;
use Illuminate\Database\DatabaseManager;
class StatsController extends Controller
{
/**
* #return array
*/
public function getLatest()
{
// Resolve dependencies out of container
/** #var DatabaseManager $db */
$db = app('db');
$database1 = $db->connection('mysql');
$database2 = $db->connection('mysql2');
// Look up 3 newest users and 3 newest blog posts
$threeNewestUsers = $database1->select("SELECT * FROM users ORDER BY created_at DESC LIMIT 3");
$threeLatestPosts = $database2->select("SELECT * FROM blog_posts ORDER BY created_at DESC LIMIT 3");
return [
"new_users" => $threeNewestUsers,
"new_posts" => $threeLatestPosts,
];
}
}

Phalcon is not able to connect to postgrsql. Here are my settings in config.php
return new \Phalcon\Config(array(
'database' => array(
'adapter' => 'Postgresql',
'host' => 'localhost',
'username' => 'postgres',
'password' => 'root',
'dbname' => 'mydb',
'charset' => 'utf8',
),
'application' => array(
'controllersDir' => __DIR__ . '/../../app/controllers/',
'modelsDir' => __DIR__ . '/../../app/models/',
'viewsDir' => __DIR__ . '/../../app/views/',
'pluginsDir' => __DIR__ . '/../../app/plugins/',
'libraryDir' => __DIR__ . '/../../app/library/',
'cacheDir' => __DIR__ . '/../../app/cache/',

DI service implementation
use Phalcon\Db\Adapter\Pdo\Postgresql as DbAdapter;
$di->set('db', function () use ($config) {
return new DbAdapter(array(
'host' => $config->database->host,
'username' => $config->database->username,
'password' => $config->database->password,
'dbname' => $config->database->dbname,
"charset" => $config->database->charset
));
});
There is no port in db connection array you used. Default postgresql port is 5432. so use this in your db connection and try to pass array directly to postgresql adapter constructor.
or
install postgres pdo /php pdo again.
I think that code is fine.
I was working a project where i had to use MySQL and PostGres.I connected my Postgresdb by following-
Below default 'db' connection string i wrote the following code inside services.php-
$di->setShared('pgphalcon', function () {
$config = $this->getConfig();
$adaptar = "PostgreSQL";
$class = 'Phalcon\Db\Adapter\Pdo\\' . $adaptar;
$params = [
'host' => "localhost",
'port' => "5432", // for localhost no need to put this line unless u change the port
'username' => "postgres",
'password' => "12345",
'dbname' => "phalcon",
];
$connection = new $class($params);
return $connection;
});
Then your controller function
do the following-
public function yourcontrollernameAction()
{
$con = $this->di->get('pghalcon');
$post = $con->fetchOne("SELECT * FROM blog ORDER BY id DESC LIMIT 1", Phalcon\Db::FETCH_ASSOC);
$this->view->data= $post;
}
For better Understanding I'd like to suggest visit this url
One thing to clarify- I was failed to do db operation by Model for PostGreSQL. That's why I used this way.
zend framework 1.x
how to receive zend db_adapter and connect to mysql having dsn like
mysql://john:pass#localhost:3306/my_db
previously was always using this way:
$connectParams = array('dbname' => MY_DB,
'password' => MY_PASS,
'username' => MY_USER,
'host' => MY_HOST,
'slave' => array(),
'maxQueryAllowedTime' => 500,
'logQueries' => false);
return new \Db_Adapter_Pdo_Mysqlreplicator($connectParams);
sure i can parse dsn and use usual way, just curious if i can use DSN directly, coz PDO can use it but i cant find how to use it through Zend Db_Adapter
If you are using ZendFramework 1.x ->Try this:-
$config = array('dbname' => 'yourDbName',
'password' => 'yourpassword',
'username' => 'root',
'host' => 'localhost',
'slave' => array(),
'maxQueryAllowedTime' => 500,
'logQueries' => false);
$adapter = new Zend_Db_Adapter_Mysqli($config);
if ($config) {
echo ' connected';
}
PostgreSQL, Oracle and many other DBMS's use SCHEMA, so, the table name is
schema_name.table_name
But CakePHP manuals not say anithing about this. What about Model, View and Controller names in the CakePHP defaults? I can use a solution like prefix, that is, where the same schema name will be used at all database operations.
PS1: please not to be confused with method Modelschema, and questions about accessing this method.
PS2: the Bill's 2006 solution is not the better one, because is not updated (I am using CakePHP2) and is not a "official cakePHP solution".
PS3: database.php have some schema attribute? What the link to CakePHP documentation?
Good news for me, there are CakePHP 2.0 documentation about SQL-Schema... No other documentation or examples, but a starting point...
In CakePHP you must define more database config.
In CakePHP 2:
set the 'schema' param to your config
create new configs for all of your schema
use the right schema in your models
For example, database conf:
public $default = array(
'datasource' => 'Database/Postgres',
'persistent' => false,
'host' => 'localhost',
'login' => 'my_db_user',
'password' => 'my_db_passw',
'database' => 'my_project_db',
'prefix' => '',
'encoding' => 'utf8',
'schema' => 'postgres'
);
public $other_schema = array(
'datasource' => 'Database/Postgres',
'persistent' => false,
'host' => 'localhost',
'login' => 'my_db_user',
'password' => 'my_db_passw',
'database' => 'my_project_db',
'prefix' => '',
'encoding' => 'utf8',
'schema' => 'other_schema'
);
If you want to use it in a model:
class AppModel extends AppModel {
public $useDbConfig = 'other_schema';
}
In CakePHP3 is the same way, just there the database is config/app.php and you must use
use Cake\Datasource\ConnectionManager;
$connection = ConnectionManager::get('default');
