Overview

Framework core build as composer module (https://getcomposer.org/).

index.php

<?php

require_once('vendor/autoload.php');
require_once('config.php');

$project = new \MyProject\EntryPoint\Site();
$project->init();

config.php

\Core\Config::setDb('default', [
  'host' => '192.168.0.1',
  'name' => ‘dbname’,
  'user' => 'user',
  'password' => 123456,
  'charset' => 'utf8'
]);

Config::registerProject('MyProject', 'default');

composer.json

{
  "require": {
    "follower/core": "dev-master"
  },
  "autoload": {
    "classmap": [
      "vendor/follower/core/backend",
      "app"
    ]
  }
}

“app” - is your app folder. Recommended backend project structure:

Api/

Controller/

Service/

EntryPoint/

Object/

Routes/

Controller/API:

In “Api” and “Controller” folders there are controllers for different application entry points (i.e. api.php and index.php).

Here are classes with methods like methodGet, methodList, which using Orm, OrmMapper, ActiveRecord, or Service for data processing.

class Entry extends Api
{
  public function methodGet($args)
  {
    $entry = \MyProject\Object\Entry::find($args[‘id’]);
    return $entry->getValues();
  }
}

Services

In “Service” folders there are service providers. You should write business logic there (not in models and controllers). Controllers are for output, models are for logic regarding only its attributes.

class UserProvider
{
   public function getUsersWithPermissions($permissions)
   {
      return \MyProject\Object\User::all()
          ->addFilter(‘permissions.alias’’, $permissions)
          ->load();
       }
}

Entry Point:

Here you should setup access rules, controllers namespace setup, register routes, and other setting for concrete entry point, and run application.

class Site extends \Core\EntryPoint
{
   public function init()
   {
      Config::set('site.language', 'ru');
      Routes::register();

      $this->setLib('\Accounting\Controller');
      $app = new App($this);
      $app->run();
   }
}

Object

Object classes are models. It contains description of data table fields, name, and relations to other entities. Here is config example.

self::$_config->setTable('User');
self::$_config->setFields([
          'name' => [
            'type' => 'varchar',
            'default' => '',
            'null' => false,
],
'password' => [
            'type' => 'varchar',
            'default' => '',
            'null' => false,
]); 

Routes

In “Routes” you can create routing class for each entry point and redefine default routing rules. Add custom route example:

\Core\Router::register(['/add', 'post'], 'Index', 'new', []);

It means that POST query to /add url will go to controller: Index, method: methodNew().

Default routing rules:

/controller/ -- Controller, methodIndex().

/controller/action -- Controller, methodAction().

Framework Philosophy

Object

Object is a model, which represents some entity

Main methods: $obj->setValue(‘property’, $value); // or setValues, for multiple values set $obj->getValue(‘property’); // or getValues, for getting all values

Also in ActiveRecord-style: $obj->property = $value; $obj->save();

Framework supports relations between models.

Collection

Represents wrapper class for objects array with methods and properties.

getData() - returns array of full objects, keys are object ids.

getHashMap(‘id’,’name’) - returns hash array, id => name

getValues(‘id’) - returns simple array of ids

Collection Stream

Uses for complex filtering objects in collections. Example:

$stream = $collection->stream();

$filter1 = function($obj) { /* complex filtering logic */  };
$stream = $stream->filter($filter1);

$filter2 = function($obj) { /* complex filtering logic */  }
$stream = $stream->filter($filter2);

//And then return filtered collection:
$stream->find(); 

Database

Raw queries

You can still write raw mysql queries using PDO.

$db = \Core\Database\PDO::getInstance();
$result = $this->db->rows("SELECT * FROM `Entry` WHERE user_id = ?", array($user_id));

Small Queries Helper

Also there is small class for trivial queries.

MySQL::insert($table, $params);
MySQL::update($table, $params, $conditions);
MySQL::delete($table, $conditions);

Examples:

MySQL::update(‘User’,  array(‘name’ => $new_name), array(‘id’ => 1));
MySQL::delete(‘User’,  array(‘id’ => 1));

QueryBuilder

For step-by-step queries constructing with different conditions. Also used internally in \Core\Orm.

composeSelectQuery() method will return raw query string for executing.

$query = new QueryBuilder(‘User’);
$query->setBaseAlias('pc')
  ->select('id', 'title', 'name')
  ->join('left', User_Catalog, 'pc', ['catalog', 'another.id'])
  ->where('somevalue', [124, 125])
  ->where('max(count)', 20, '<')
  ->where('title', '%test', 'like')
  ->where('test', null);
  ->orderBy('id', 'asc')
  ->groupBy('param1')
  ->limit(20);

echo $query->composeSelectQuery();

Orm

Layer for working with Database, which encapsulate queries and supports relations.

Main methods:

Orm::create($class_name);
Orm::save($object);
Orm::delete($object);

Orm::find($class_name, $filterFields, $filterValues, $params);
Orm::findOne($class_name, $filterFields, $filterValues, $params);
Orm::load($class_name, $id);
Orm::count($class_name, $filterFields, $filterValues);

Simple examples:

$user = Orm::create(‘User’);
$user->setValues(array(‘name’ => $name, ‘password’ => $password));
Orm::save($user);

$users = Orm::find(‘User’, array(‘name’, ‘type’), array($name, $type)));
$user = Orm::load(‘User’, 12);
Orm::delete($user);

Mapper

Another class, more flexible.

$mapper = OrmMapper::create(User);
$mapper->setFields(['test', 'name', 'amount']);
  ->setFilter(['test', 'name', 'amount'], [1,2,3]);
  ->load();

$users  = $mapper->getCollection();

ActiveRecord

Convenient way to work with objects. Some examples:

$users = User::all()
  ->addFilter(‘type’, $id)
  ->load()
  ->getCollection();

$user = User::find($id);
$user->name = ‘Peter’;
$user->save();
