README

actually this library is a light PHP dependency injector

why to use this library.

if you are a PHP developer, you will know that,PHP has a feature called Reflection,with that,you can do cool things,as follows: you can create a Object dynamic,even there is some dependences,this library will create it for you,not only but also,you can call any public method of it ,its dependences will also be parsed.

how to use

first,we assume that there are two class,code is here:

class Apple{
  public function  shape(){
    return 'red';
  }
}

class Person{
  public function eat(Apple $apple){
    echo $apple->shape();
  }
}

class  Hunter{
    protected $weapon;
    public function __construct(Weapon $weapon)
    {
        $this->weapon=$weapon;
    }

    public function showWeapon(){
        $this->weapon->display();
    }

    private static function  getInstance(Weapon $weapon){
        return new self($weapon);
    }

    public static function create(Weapon $weapon){
        return new self($weapon);
    }
}

class  Weapon{
    private $name;
    private $price;
    private $type;
    private $level;
    public function __construct($name,$price,$type,$level)
    {
        $this->name=$name;
        $this->price=$price;
        $this->type=$price;
        $this->level=$level;
    }

    public function display(){
        echo 'weapon detail of'.$this->name.':'.$this->price.'-'.$this->type.':'.$this->level;
    }
}

as you see,there are two class called Apple and Person, if you want to call eat method of Person ,you can do like this. following code show how you can use this library.

$defaultConfig=[
    'name'=>"saberyjs",
    'price'=>100,
    'type'=>'Melee',
    'level'=>4
];
$config=[
    'method'=>[
        'getInstance',
        'create'
    ],
    'factory'=>[
        Hunter::class=>function(){
            return new Hunter($routeHelper->get(Weapon::class));
        }
    ]
];
$reflHelper=new ReflHelper($config,$defaultConfig);
$reflHelper->callMethod($reflHelper->get(Apple::class),'eat');

$reflHelper->get(Hunter::class)->display();

as you see ,this library is very easy to use.totally,you can follows:

• call $reflHelper->get() can get a object
• call $reflHelper->callMethod() can call a method of a object
• call $reflHelper->callStaticMethod() can call static method

if you look upper code carefully,you will find we pass two args($config,$defaultConfig) when we create ReflHelper,$config contain two main key(method,factory), the method key specify the method that will be called when library create instance,if class`__constructor not exist,$defaultConfig contain default value that will be used if it is a dependency of other

ReflHelper will do everything for you,even,you do not need to create Apple object,not only but also,this library also also support a function : upper code will create instance of specified class,parse dependency
