PHP load array values from file and return them as array

I have file:

en.php

<?php
$lang['word'] = 'word';
$lang['text'] = 'text';

index.php

<?php
function load($file) {
    include $file . '.php';
    echo $lang['word'];
    echo $lang['text'];
}

load('en');

Question:

How to get array values from en.php and return them as array with load().

How to process file to return each array value in load() to use it in index.php like this:

   echo $lang['word'];

I know that include function view file in global scope but variables are in local scope. There for I am looking in "return as array" solution.

Edit: I want to separate languagse in files en.php, de.php, ru.php ... and then load them into index.php with load. Then retrieve them and echo as $lang['text'].

Your code is correct

<?php
function load($file) {
    include $file . '.php';
    return $lang;
}

print_r(load('en'));

You can use the global declaration to make $lang a global variable:

function load($file) {
    global $lang;
    include $file . '.php';
    echo $lang['word'];
    echo $lang['text'];
}

you are including the file en.php inside the function so $lang is local for the function and you can use them directly.

function load($file) {
    include $file . '.php';
    echo $lang['word'];
    echo $lang['text'];
}

If you include the file outside the function then $lang will be global for the function and you can access this by using global keyword.

like:

include 'en.php';
function load() {
    global $lang;
    echo '<br>'.$lang['word'];
    echo '<br>'.$lang['text'];
}

en.php (or lang_en.php)

<?php
    class lang_en {
        var $lang = array();
        public function __construct() {
            $this->lang['word'] = 'word';
            $this->lang['text'] = 'text';
        }
        public function get_lang() {
            return $this->lang;
        }
    }
?>

index.php

<?php
    function load($file) {
        include $file . '.php';
        $class_name     = 'lang_' . $file;
        $lang_instance  = new $class_name();
        $get_lang       = $lang_instance->get_lang();
        echo $get_lang['word'];
        echo $get_lang['text'];
    }
    load('en');
?>

Untested & it's early - but this should work...

you can simply do a return $lang in your en.php file and then assign it to a variable in the load function: $load = include $file . '.php';
