point-core
, (*1)
Overview
This is a PHP IoC/DI Module Container.It can inject instance of object through the @Annotation on PHPDoc., (*2)
Features
- Dependency Injection
- Inversion of Control
- File/Class Lazy Loading
- Configuration by PHP Annotation
- Rich Module Framework
Getting and Start (composer)
Install point-core from composer repository
composer require samejack/point-core
Get first object from context
<?php
include 'vendor/autoload.php';
use point\core\Context;
use point\core\Bean;
class Bar
{
public function __toString()
{
return 'Bar!';
}
}
$context = new Context();
$context->addConfiguration(array(
array(
Bean::CLASS_NAME => 'Bar'
)
));
$bar = $context->getBeanByClassName('Bar');
echo $bar; // print Bar!

PHP Example (Snippet Code):
General Inject
<?php
use point\core\Context;
use point\core\Bean;
class Foo
{
/**
* @Autowired
* @var Bar
*/
private $_bar;
public function getBar()
{
return $this->_bar;
}
}
class Bar
{
}
$context = new Context();
$context->addConfiguration(array(
array(
Bean::CLASS_NAME => 'Foo'
),
array(
Bean::CLASS_NAME => 'Bar'
)
));
$foo = $context->getBeanByClassName('Foo');
var_dump($foo->getBar()); // print Class Bar
Inject After
<?php
use point\core\Context;
use point\core\Bean;
class Foo
{
/**
* @Autowired
* @var Bar
*/
private $_bar;
public function getBar()
{
return $this->_bar;
}
}
$context = new Context();
$context->addConfiguration(array(
array(
Bean::CLASS_NAME => 'Foo'
)
));
$foo = $context->getBeanByClassName('Foo');
var_dump($foo->getBar()); // print NULL on unload Bar Class
// load Bar class
class Bar
{
}
// set configuration
$context->addConfiguration(array(
array(
Bean::CLASS_NAME => 'Bar'
)
));
var_dump($foo->getBar()); // print Class Bar
Inject by ID of Bean
use point\core\Context;
use point\core\Bean;
class Foo
{
/**
* @Qualifier("bar.2")
* @var Bar
*/
private $_bar;
public function getBar()
{
return $this->_bar;
}
}
class Bar
{
private $_name;
public function __construct($name)
{
$this->_name = $name;
}
public function toString()
{
return $this->_name;
}
}
$context = new Context();
$context->addConfiguration(array(
array(
Bean::CLASS_NAME => 'Foo'
),
array(
Bean::CLASS_NAME => 'Bar',
Bean::ID => 'bar.1',
Bean::CONSTRUCTOR_ARG => ['i am first.']
),
array(
Bean::CLASS_NAME => 'Bar',
Bean::ID => 'bar.2',
Bean::CONSTRUCTOR_ARG => ['i am second.']
)
));
$foo = $context->getBeanByClassName('Foo');
var_dump($foo->getBar()); // print Class Bar
PDODB inject example
class MyControllerA
{
/**
* @Autowired
* @var PDO
*/
private $_pdo;
public function getPdo()
{
return $this->_pdo;
}
}
class MyControllerB
{
/**
* @Autowired
* @var PDO
*/
private $_pdo;
public function getPdo()
{
return $this->_pdo;
}
}
$context = new Context();
$context->addConfiguration(array(
array(
Bean::CLASS_NAME => 'MyControllerA'
),
array(
Bean::CLASS_NAME => 'MyControllerB'
),
array(
Bean::CLASS_NAME => 'PDO',
Bean::CONSTRUCTOR_ARG => ['mysql:host=localhost;dbname=mysql', 'root', 'password!']
)
));
$ctrlA = $context->getBeanByClassName('MyControllerA');
var_dump($ctrlA->getPdo()); // print: class PDO#11 (0)...
$ctrlB = $context->getBeanByClassName('MyControllerB');
var_dump($ctrlB->getPdo()); // print: class PDO#11 (0)...
