Question

is there a way to create a class method for a class from another class?

Example:

class A
{
    public function makeMethod()
    {
        $this->b = new B();
        //create a method for class B such as a __call() method
        //to catch an error trying to access a non existant class B method
        if (!method_exists($this->b, "__call")
            // create __call() method
    }
}

class B
{

}

Have a look at this example :

class A
{
    public function makeMethod()
    {
        $this->b = new B();
        //create a method for class B such as a __call() method
        //to catch an error trying to access a non existant class B method

        $this->b->doit();
    }
}

class B
{

    public function __call($name,$args)
    {
        echo "function called: $name with arguments: $args";
    }

}

$a = new A();

$a->makeMethod();

?>

This will output :

function called: doit with arguments: Array

So, in a way, we called a non-existant function of class B and we still can do something with that…. e.g. in your __call method in class B couldn’t you point the execution to some callback function (even of class A)? Why “create” it? (Don’t think from the developer’s point of view, unless you absolutely have to… :-))

Just an idea…

A glimpse from Page/Module Execution handling in Minima Framework :

public function  __call($name, $arguments=NULL)
{
    $function_name = "_".$name;

    $trace = debug_backtrace();

    $moduleCall = false;

    if (isset($trace[2]))
    {

        if (isset($trace[2]['object']))
        {
        $trace = $trace[2]['object'];

        if (is_subclass_of($trace, 'mmModule'))
            $moduleCall = true;
        }
    }

    $args = $this->matchArguments($name, $arguments);

    if ($moduleCall) { $this->redirect ($name, $arguments); }
    else
    {
        $this->Result = call_user_func_array(array($this, $function_name), $args);

        $this->loadTemplate($name);
    }
}

P.S. Simply because I’ve already created a 100% PHP framework myself, and perhaps I know what you might need…
