outputs ...

Hope that helps.

@RQuadling - Thanks for helping, but that actually wasn't what I wanted. In my original filters.php I have

App::before(function($request)
{
	$url = explode('.', $request->server('HTTP_HOST'));
	

    $langcode = $url[1];

    $languages = ['en','fr'];
 
    if ( in_array($langcode, $languages) ){
    	echo "yes";
        App::setLocale($langcode);
    }else{
    	echo "no";
    }

});

And this code allows me to be able to select what languages i'm using via the $languages array. So what I'm trying to do is create a php file that has a list of languages that I will be using, so instead of doing something like this

$languages = ['en','fr', 'es', 'ch', 'af', 'de', 'hr', 'ar', 'ru', 'mn', 'el', 'he', 'ja', 'pol',];

where if I have alot of languages to use it will start to look untidy. So all I would have to do is call it like this

$languages = Config::get('languages.supportedLang');

now the problem comes in around this line

if ( in_array($langcode, $languages) )

this line checks what the $langcode is and then it will have a look at $languages to see if it is in that array and if it is then it would do what it's suppose to do.

But $languages needs to be an array. Where the languages would look like this if I print_r $languages

Array
(
    [0] => en => Array
                (
                    [name] => English
                    [dir] => ltr
                )
    [1] => es => Array
                (
                    [name] => Spanish
                    [dir] => ltr
                )
    [2] => fr => Array
                (
                    [name] => French
                    [dir] => ltr
                )
)

Is this explanation better? I'm not sure how to word what I need.

Or use array_key_exists()

or isset($languages[$langcode])

Many cats were skinned.

@RQuadling - Yep that worked as I wanted. Thank you soooo much

I'd go with the isset().
