Read array in php?

Question

I'm trying to add some custom user meta on the registeration. For example, I have field to set a fruit :

function some_fruits($fruit= false) {
    $fruits= array();
    $fruits['1'] = 'Apple';
    $fruits['2'] = 'Banana';
    $fruits['3'] = 'Apricot';
    if ($fruit) {
        return $fruits[$fruit];
    } else {
        return $fruits;
    }
}

But when I call this field with

$display_fruit = get_user_meta($user_id, 'fruit', true);

it displays 1 instead of Apple. How can I solve this ?

Answer 1

Fastest way would be something like this:

$fruit_id = get_user_meta($user_id, 'fruit', true); //returns 1
$display_fruit = some_fruits($fruit_id); //will return 'Apple'
