PHP Models

A PHP library that allows you to easily create and define your models using PDO

Features

  • PDO wrapper
  • FETCH_INTO made easy
  • Model helper

Installation

$ composer require lodev09/php-models

Usage

DB.php

The main \Models\DB class is a PDO wrapper used to make CRUD much easier. It is a forked code from the php-pdo-wrapper-class

// connect to your database. Store the $db instance globally -- you only need to connect to your db ONCE!
$db = new \Models\DB(DB_HOST, DB_NAME, DB_USER, DB_PASSWORD);

Available CRUD methods

  • $db->insert($sql, $binds) or $db->insert($table, $values)
  • $db->select($sql, $binds)
  • $db->selectRow($sql, $binds) (same with select but will return single row)
  • $db->update($sql, $binds) or $db->update('table', $values)
  • $db->delete($sql, $binds) or $db->delete('table', $filters)

The default style is PDO::FETCH_OBJ

Example:

$users = $db->select("SELECT * FROM users WHERE active = 1 AND username = :username", array('username' => 'lodev09'));
var_dump($users);

Model.php

The \Models\Model class is a parent class that can be inherited to a Model class. Inheriting this class allows you to automatically map the result "row" into your model class (table). This class basically uses the PDO::FETC_INTO style and made it easier for you. Here are the steps to link your table into a class:

  1. Initiate the \Models\DB instance (see above)
$db = new \Models\DB(DB_HOST, DB_NAME, DB_USER, DB_PASSWORD);
\Models\Model::setDb($db);
  1. Create your model class. For example, a User.php class
namespace Models;

class User extends Model {
    public function getName() {
        return $this->name;
    }
}
  1. Register your table to your custom class
// somewhere in your init.php
\Models\User::register('users');

Now, you can directly get the User instance from a query. Example:

$user = \Models\User::row("SELECT id, name FROM users WHERE id = 1 AND active = 1");
// you can call the getName() method now
if ($user) {
    $name = $user->getName();
    echo 'His name is '.$name;
}
