PHP and Zend framework - php

Question

How can I easily implement queries in Zend framework?

Answer 1

Check this document:
Zend Framework Database Quick Start (PDF)

Answer 2

You can use doctrine2
Doctrine project.
There is a module compatibile with ZF3
DoctrineModule.
You can use QueryBuilder that brings creation of query to object manipulation.

Answer 3

You can use the Zend Db Adapter object like so:
$sql = 'SELECT * FROM bugs WHERE bug_id = ?';
$result = $db->fetchAll($sql, 2);

Answer 4

Use Zend_Db and just create a $db Object using Zend_Db Factory Method, and then create SQL Statements using Zend_Db_Select Class and pass the $select SQL Statement to the fetch* (fetchRow, fetchAll...) Methods.

Answer 5

1.Config:
config/autoload/dbAdapter.local.php
<?php
return array(
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=name;host=localhost',
'username' => 'root',
'password' => 'root',
),
'service_manager' => array(
'abstract_factories' => array(
'Zend\Db\Adapter\AdapterAbstractServiceFactory',
),
),
);
Implementation:
public function testAction()
{
$username = 'user';
$sql = "SELECT email FROM users WHERE username = ?";
$statement = $this->getDbAdapter()->createStatement($sql, array($username));
$result = $statement->execute()->current();
}
protected function getDbAdapter()
{
if($this->dbAdapter == null) {
$this->dbAdapter = $this->getServiceLocator()->get('Zend\Db\Adapter\Adapter');
}
return $this->dbAdapter;
}

Answer 6

Zend framework has abstract_factories ,it allows us to handle multiple DB queries :
Zend\Db\Adapter\AdapterAbstractServiceFactory
Need to set Service Manager :
'service_manager' => array(
'abstract_factories' => array(
'Zend\Db\Adapter\AdapterAbstractServiceFactory',
),
),
Configure adapters in config/autoload/local.php
db' => array(
'adapters' => array(
'database1' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=userDB;host=localhost',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
),
etc...
),
),
Configure adapters in config/autoload/global.php
return array(
'db' => array(
'adapters' => array(
'database1' => array(
'username' => 'root',
'password' => '',
),
),
),
);
Call adapters
$dbmanager->get('database1');
Use in Model
use Zend\Db\TableGateway\AbstractTableGateway;
use Zend\Db\Adapter\Adapter;
class UserTable extends AbstractTableGateway
{
protected $table ='user';
public function __invoke(Adapter $adapter)
{
$this->adapter = $adapter;
$this->initialize();
}
public function fetchAll()
{
$resultSet = $this->select();
return $resultSet->toArray();
}
}
