define a closure as method from class

Question

i\'m trying to play with php5.3 and closure.

I see here (Listing 7. Closure inside an object : http://www.ibm.com/developerworks/opensource/library/os-php-5.3new2/in

Answer 1

As of PHP 5.4.0 Alpha1, you can access $this from within the context of an object instance:

_name = $name;
    $this->_color = $color;
  }

  public function greet($greeting)
  {
    $func = function() use ($greeting) {
      echo "$greeting, I am a {$this->_color} dog named {$this->_name}.";
    };

    $func();
  }
}

$dog = new Dog("Rover","red");
$dog->greet("Hello");

You can also do this:

$dog = new Dog("Rover", "red");
$getname = Closure::bind($dog, function() { return $this->_name; });
echo $getname(); // Rover

As you can see, it's possible to easily mess with private data... so be careful.
