Passing global variables to dispatch router library php

Question

So I'm using noodlehaus / dispatch for my website routhing. I want to pass some variables from main scope like $currentLang to route(...), but I get this error:

Notice: Undefined variable: currentLang in C:\xampp\htdocs\_PERSONAL\newSite\index.php on line 18

Here's a part of my code.

require './functions/dispatch.php';

$currentLang = 'en';

route('GET', '/resume', function () {
    $data['lang'] = $currentLang;

    return response(
        phtml(__DIR__.'/views/resume', ['data' => $data ])
    );
});

dispatch();

Please help me with this. Thanks.

Answer 1

adding global $data; solved the problem:

    require './functions/dispatch.php';

    $currentLang = 'en';

    route('GET', '/resume', function () {
        global $currentLang;
        $data['resume'] = json_decode(
            file_get_contents("assets/json/resume-".$currentLang.".json"), true
        );

        return response(
            phtml(__DIR__.'/views/resume', ['data' => $data ])
        );
    });

Or like this:

    require './functions/dispatch.php';

    $currentLang = 'en';

    route('GET', '/resume', function () use ($currentLang){
        $data['resume'] = json_decode(
            file_get_contents("assets/json/resume-".$currentLang.".json"), true
        );

        return response(
            phtml(__DIR__.'/views/resume', ['data' => $data ])
        );
    });
