PHP Class Function Parameters - Any Number of Parameters, call_user_func

[Demonic]

Okay, heres the thing, I'm building my semi cms, its used for a majority of my projects just to get me started with a basic of everything I need.  Backend wise and what not.  It's built off of codeigniter and I'm trying to manipulate a feature that they have in my system.

 

I've created a semi module system which acts just like the controller system codeigniter has, but what I don't have is the extra parameters being passed to my class function.

 

					$action = '_default';
					//show default action
					if( method_exists($class,$action))
					{	
						if( ($this->perms->exists("main_" . $class_name . $action) && $this->perms->has("main_" . $class_name . $action)) OR !$this->perms->exists("main_" . $class_name . $action))
						{
							$url = $this->uri->segment_array();
							return call_user_func(array($class,$action),'test');
						}
						else
						{
							//user has no permissions
							return $this->error("You have no permissions");
						}
					}
					else
					{
						//return error saying default module does not exists
						return $this->error("Default Action does not exists!");
					}

 

Heres a snipet from my code.

 

Above you see $url, that grabs all the urls,

 

Basically I want to pass the results of the urls to the current class function withing using an array, you see how I have "test", thats exactly how I want the parameters to output not: Array()..

 

How can I pass the array (with a foreach) statement to that call_user_func, without "eval"?

 

							$params = "'" . implode("','",$url) . "'";
							eval("call_user_func(array(\$class,\$action),{$params});");

 

Is the only way I can see it being done.

You mean like this -

call_user_func(array($class, $action), $url);

?

 

Then in call_user_func(), you can loop through $url for all the params.

Not really.

 

$url outputs an array, and if I passed $url, I would have to treat the parameter like an array.

 

Array

(

    [1] => admin

    [2] => module

    [3] => folio

    [4] => test

)

 

Heres my default action:

 

public function _default($test)
{
	echo $test;
	$this->template->load( array(
		array(
			"admin/modules/folio/manage",
			array('results' => $this->instance->folio_model->get_array()),
		),
	),"admin");
}

 

If I don't have any actions created for the parameter I provided, it will be come a function parameter.

 

http:// localhost/portfolio/admin/module/folio/test

 

If the function "test" isn't created in the url, that will become the first parameter in the default function

 

_default("test")

 

If there are more url segments it will automatically become the next parameter in the function:

 

http://localhost/portfolio/admin/module/folio/test/test2

 

_default("test","test2")

 

thats only if I haven't created a function named "test".

 

If I created a function named test:

 

it'll look like:

 

test("test")

 

What I'm trying to figure out is if theres an alternative to "eval" to executing that function with the parameters.  Heres what I got so far:

 

/**

 * This function is used to load built in and user created
 * modules.  Plug and play system for easibility.

public function module($module=null,$action=null)

	switch( $module )

			return $this->_module_groups();
		break;
		case "manage":
			if( !$this->perms->has("main_admin_modules"))
				return redirect("admin/no_permissions");
			return $this->_module_manage();
		break;
	}
