Answer 1

If I were you, I'd do it like this:

/inc/lang/en.lang.php

define('_HELLO', 'Hello');

/inc/lang/fa.lang.php

define('_HELLO', 'سلام');

index.php

// $_SESSION['lang'] could be 'en', 'fa', etc.
require_once '/inc/lang/' . $_SESSION['lang'] . 'lang.php';

echo _HELLO;

Benchmark: Constants vs. Variables

Here you see why I offered using Constants not Variables:

const.php

echo memory_get_usage() . '
';   // output: 674,576

for ($i = 0; $i <= 10000; $i++) {
    define($i, 'abc');
}

echo memory_get_usage() . '
';   // output: 994,784

var.php

echo memory_get_usage() . '
';   // output: 674,184

for ($i = 0; $i <= 10000; $i++) {
   $$i = 'abc';
}

echo memory_get_usage() . '
';   // output: 2,485,176
