How to add methods dynamically

I'm trying to add methods dynamically from external files. Right now I have __call method in my class so when i call the method I want, __call includes it for me; the problem is I want to call loaded function by using my class, and I don't want loaded function outside of the class;

Class myClass
{
    function__call($name, $args)
    {
        require_once($name.".php");
    }
}

echoA.php:

function echoA()
{
    echo("A");
}

then i want to use it like:

$myClass = new myClass();
$myClass->echoA();

Any advice will be appreciated.

Solution 1:

You cannot dynamically add methods to a class at runtime, period.*
PHP simply isn't a very duck-punchable language.

_{* Without ugly hacks.}

Solution 2:

Is this what you need?

$methodOne = function ()
{
    echo "I am  doing one.".PHP_EOL;
};

$methodTwo = function ()
{
    echo "I am doing two.".PHP_EOL;
};

class Composite
{
    function addMethod($name, $method)
    {
        $this->{$name} = $method;
    }

    public function __call($name, $arguments)
    {
        return call_user_func($this->{$name}, $arguments);
    }
}


$one = new Composite();
$one -> addMethod("method1", $methodOne);
$one -> method1();
$one -> addMethod("method2", $methodTwo);
$one -> method2();

Solution 3:

You can dynamically add attributes and methods providing it is done through the constructor in the same way you can pass a function as argument of another function.

class Example {
    function __construct($f)
    {
       $this->action=$f;
    }
}

function fun() {
   echo "hello\n";
}

$ex1 = new class('fun');

You can not call directlry $ex1->action(), it must be assigned to a variable and then you can call this variable like a function.
