Features

• Allows you to perform complex queries with little code

  • select
  • insert
  • update
  • delete
  • where
  • params
  • count
  • orderBy
  • groupBy
  • joins
  • limit

• Hydration Ability to return a collection of objects:

  • into(Demo::class)

Getting Started

Create a new PDO instance, and pass the instance to Query:

use Goldoni\Builder\Query;
....
$pdo = new \PDO('mysql:dbname=goldoni;host=localhost;charset=utf8', 'root', 'root');
$query = (new Query($pdo))

Prerequisites

What things you need to install the software and how to install them

"require": {
    "php": ">=7.2.0"
}

Installing

composer require goldoni/php7.2-query-builder

Examples

select

$query = (new Query())->from('users')->select('first_name');

build the query below

SELECT first_name FROM users

insert

$query = (new Query($this->pdo))
            ->insert(
                'users',
                [
                    'first_name' => ':first_name',
                    'last_name'  => ':last_name',
                    'email'      => ':email',
                    'mobile'     => ':mobile',
                    'phone'      => ':phone',
                ]
            );
            
$query1 = (new Query($this->pdo))
            ->insert('users')
            ->value([
                'first_name' => ':first_name',
                'last_name'  => ':last_name',
                'email'      => ':email',
                'phone'      => ':phone'
            ]);

build the query below

INSERT INTO users (first_name, last_name, email, mobile, phone) VALUES (:first_name, :last_name, :email, :mobile, :phone)

insert with ->execute()

$data = [
    'id' => 12,
    'first_name' => 'Joe3',
    'last_name'  => 'Doe3',
    'email'      => 'joe@contact.de',
    'phone'      => '+0172222222'
];

$query = (new Query($this->pdo))
    ->insert(
        'users',
        [
            'id' => ':id',
            'first_name' => ':first_name',
            'last_name'  => ':last_name',
            'email'      => ':email',
            'phone'      => ':phone'
        ]
    )->params($data)
    ->execute();

update

    'first_name' => 'Joe3',
    'last_name'  => 'Doe3',
    'email'      => 'joe@contact.de'
];
$query = (new Query($this->pdo))
        ->update(
            'users',
            [
                'first_name' => ':first_name',
                'last_name'  => ':last_name',
                'email'      => ':email'
            ],
            2
        )
        ->params($data);
            
$query1 = (new Query($this->pdo))
            ->update('users')
            ->set([
                'first_name' => ':first_name',
                'last_name'  => ':last_name',
                'email'      => ':email'
            ])
            ->where('id = :id')
            ->params($data);

build the query below

UPDATE users SET first_name = :first_name, last_name = :last_name, email = :email WHERE (id = :id)

update with ->execute()

$data = [
    'first_name' => 'Joe',
    'last_name'  => 'Doe',
    'email'      => 'joe@contact.de',
    'phone'      => '+0172222222'

$demo1 = $demos[0]; 

// get_class($demo1) === Demo::class  

echo $demo1->firstName; 

$demo2 = (new Query($this->pdo))
            ->from('users', 'u')
            ->where('id = :id')
            ->into(Demo::class)
            ->params(['id' => 2])
            ->fetch();
            
// get_class($demo2) === Demo::class      

echo $demo2->firstName;

var_dump($demo1 instanceof Demo::class); // TRUE
var_dump($demo2 instanceof Demo::class); // TRUE
