Application Design

[NixNod]

Hello, guys.

 

I got an question, I'm building an application skelecton that I'll use

for all others applications I'll develop, "Like an Framework".

I got some ideas, but I don't know which design implements.

 

Background:

The system will run arround the main class called "Core"

This class will have an Method for loading other classes (Singleton), this main class

core is used to log errors and others thigs, for example:

I got the DB class, when an error occours, it will log on Core.

So all child classes is loaded via "Core" and I got this Design:

 

<?php
$Core = new Core;
$Core->GetInstance('Scaffold'); //Loads the class and create the var object inside the core class
$Core->Scaffold->SayHello(); //Method inside Scaffold class.
?>

 

But to use the "Core" inside Scaffold (To call Log & Error functions) I

must declare Core as Global.

 

I Want something like that to application be a little more centred, and

not have a loads of objects.

 

Question(s):

1 This is an good design?

2 Other design can help me more?

3 There is an other way to optimize it?

4 The "Core" classe would be Global, I know it is not

good, what's the better way?

1. No.

2. Yes.

3. Yes.

4. Where do I start...

 

But to use the "Core" inside Scaffold (To call Log & Error functions) I
must declare Core as Global.

 

This is not true.

 

public function scaffoldFactory(){
   $this->scaffold = new Scaffold($this);
}
public function __construct(Core $core){
   $this->core = $core;
}

 

On a sidenote, if you declare $Core in the global space, you don't need to explicity declare it global. I would NEVER do something like this though:

 

public function doSomething(){
   global $core;
   $core->doSomethingElse();
}

 

You're asking for trouble with something like that.

 

In any case, you need to rethink this.

 

I usually recommend this tutorial for people just getting interresseted in centralizing application flow, avoiding globals and/or MVC.

Sup, verry good.

I'v tested that, but if I want an dynamic thing like:

members/view/123

 

(123) is the ID that I'll get on DB.

 

What I'll do?

Nevermind, I'v just created an Function inside Router that get the segment by the number

 

<?php
    public function GetSegment($Seg) {
        $Route = (empty($_GET['route'])) ? '' : $_GET['route'];
        $Route = trim($Route, '/\\');
        $Segments = explode('/', $Route);
        return $Segments[$Seg-1];
    }
?>

 

So inside the View function inside Controller_Member

I'v added It:

<?php
print $this->Registry['Router']->GetSegment(4);
?>

 

Thanks
