Define/include "globally available" arrays and functions

Hello,

I'd like to define some arrays and functions that I can access "globally" in all controllers/models/views.
For example I need to define an array of available currencies:

PHP Code:

$currencies = array("EUR","USD"); 


And some functions e.g. to display numbers differently depending on the users country as some use decimal points or commas.

Where would I put those arrays and functions and how would I include them so they are available from everywhere?

Thank you very much for your help
Tom

For your array of currencies, define a new config file. You can load it anywhere you need it.

PHP Code:

// load the file
$config = config('MyConfig');

// get some values...
$config->currencies; 


For your functions, if it's only simple functions, create a helper file. If it's more complicated and you need a class, maybe create a library.

Also, have a look at the number_to_currency function in the number helper: http://codeigniter.com/user_guide/helper...o_currency

@tomsenner,

You could declare CONSTANTS:

index.php

Code:

<?php
defined('CURRENCIES') ?: define('CURRENCIES', array("EUR","USD") );
...
...

<?php namespace MyConfig

use CodeIgniter\Config\BaseConfig;

class MyConfig extends BaseConfig
{
Public $array=[]
}



To call it create new instance of myconfig

$mc = new MyConfig() ;
$mc->$array;

$this->config = config('yourConfig');

Thank you. Is it ok to declare arrays as a constant? Was the file intended for that?
My array might even change at some point if we add more currencies.

Thanks a lot for the info.
Instead of creating a new helper file, I could also use app/Common.php, right? It says it's like the Master helper file and loaded already anyway. Any disadvantage of using this file?

Helper is fine you call fuction in backend and in html code too

Sms_helper. Php
Helper(sms)

Call in fuction helper thats it

You can use the new Files autoloading available to the Autoloader as of v4.1.2. Create a class containing your global functions and defining your currencies as constant.

PHP Code:

// example filename: my_global_functions.php

define('CURRENCIES', array('EUR', 'USD'));

if (! function_exists('foo'))
{
    function foo()
    {
            // logic here
    }
} 


After creating the file, write the path of the file in your app/Config/Autoload.php file, particularly in the $files property.

PHP Code:

// app/Config/Autoload.php

public $files = [
    'path/to/my_global_functions.php',
];

Missing quotes around CURRENCIES.

define(CURRENCIES, array('EUR', 'USD'));

This is great - thank you so much. Where would be the best place to store the new file? In app/helpers ?
