Call an array including into another file with php

Question

Why this do not work and how can I solve it please ?

Main page:

$a = include 'module_a.php';
print_r($a);

module_a.php page:

function go() {
    include 'datas.php';
    return $array;
}

datas.php page:

$array = array();
$array[10] = 'bla';
$array[11] = 'blo';
return $array;

I do not have any error in the console except that no code is print.

Thanks for your help.

Answer 1

I suppose it should be somehow like this:

include 'module_a.php';
$a = go();
print_r($a);

To your post update: datas.php doesn't have to return $array

Answer 2

Nothing is printed because you define function go but you never execute it. Do:

include 'module_a.php';
print_r(go());

Answer 3

You forgot to call go function

index.php

<?php

$a = include 'module_a.php';
print_r($a);

module_a.php

function go() {
    include 'datas.php';
    return $array;
}

return go();

datas.php

<?php
$array = array();
$array[10] = 'bla';
$array[11] = 'blo';

return $array;
