How to set global settings variables

PHP
1

Hi, I want to set up in settings table variables for pagination, admin_email and so on. This vars will be set up only once and I need them to call for different purposses.
for example.

....
.
$content = new Content(); 
$content->id = "$id";
$content->name = "$name";
..
$content->create(); 
//send email notification
$from = this var is under Settings class
$to = this var is under Settings class
$content->send_email($from, $to, $name);

Obviosly I cannot access them with Settings::$site_admin_email
and I dont want to access with instantiating Settings object with $set = new Settings();
and then getter from settings.
Because it will store only one row of information I guess there is simplier way to do this.

Why?


class Settings
{
    static protected
        $store = array();
    
    static public function Get($key){
        return self::$store[$key];
    }
    
    static public function Set($key, $value){
        self::$store[$key] = $value;
    }
    
    static public function Has($key){
        return array_key_exists(
            $key,
            self::$store
        );
    }
}

thanks for fast response Anthony,
I tried your class


<?php


class Settings{
    public $site_name;
    public $site_desc;
    public $site_meta;
    public $site_admin_email;
    public $site_receive_email;
    public $site_pagination_per_category;
	
   static protected
        $store = array();
    
    static public function Get($key){
        return self::$store[$key];
    }
    
    static public function Set($key, $value){
        self::$store[$key] = $value;
    }
    
    static public function Has($key){
        return array_key_exists(
            $key,
            self::$store
        );
    }
} 


?>

and I got this error message
Fatal error: Access to undeclared static property: Settings::$site_admin_email

You need to ‘set’ the variables to be stored first. :wink:


#somewhere at the start of your application
Settings::Set('admin.email.address', 'you@example.org');
Settings::Set('admin.email.subject', 'Website Notification');
Settings::Set('site.domain.name', 'example.org');

#anywhere else in your application, but within the same request
mail(
    Settings::Get('admin.email.address'),
    Settings::Get('admin.email.subject'),
    sprintf(
        'Hey, someone has just registered at &#37;s!',
        Settings::Get('site.domain.name')
    )
);

#which, is the same as...
mail(
    'you@example.org',
    'Website Notification',
    'Hey, someone has just registered at example.org!'
)
