Question

I try to create some sort of setup class, like global values for the page.

The PHP-code

class globals
{
    public $page;

    public function __construct()
    {
    }

    public function set_page($value)
    {
        $this->page = $value; // Maybe from a database
    }
}

class get
{
    public function page()
    {
        $globals = new globals();
        return $globals->page;
    }
}

$globals = new globals();
$globals->set_page('My value');

echo get::page(); // Short function to be in a template

Question

• My class forget the value I set. Why is that?
• Do I have to use global variables?
• Is this the correct approach for the problem?

Answer 1

Do I have to use global variables?

Not, if your can use PHP 5.3

Is this the correct approach for the problem?

Better to use a generic class for this, or use static properties of objects

<?php

class globals
{
    public static $page;

    public function __construct()
    {
    }

    public function set_page($value)
    {
        self::$page = $value; // Maybe from a database
    }
}

class get
{
    public static function page()
    {
        return globals::$page;
    }
}

$globals = new globals();
$globals->set_page('My value');

echo get::page(); // Short function to be in a template

P.S.
But this is not a nice approach
