Reading array from custom fields

Question

I am saving posts by the current user's name. Furthermore, I am saving an array object - $ganalytics_settings - to the post in a custom field. With the following code I am trying to load the array for the username, with a specific post title:

    function get_custom_field_for_current_user( $customFieldName ) {

        $current_user = wp_get_current_user();          
        global $wpdb;
        $id = $wpdb->get_row("SELECT ID FROM wp_posts WHERE post_title = '" . $current_user->user_login . "' && post_status = 'draft' && post_type = 'post' ", 'ARRAY_N');

        return get_post_meta((int)$id[0], $customFieldName);
    }

However, I am getting back the following object:

Instead I would like to get back the following:

Any suggestions why my function gives me back an array in array?

I appreciate your reply!

I don't know if I understood you, but if your function returns the array with first key being an array, then just always return that first key

function get_custom_field_for_current_user( $customFieldName ) {

    $current_user = wp_get_current_user();
    global $wpdb;
    $id = $wpdb->get_row("SELECT ID FROM wp_posts WHERE post_title = '" . $current_user->user_login . "' && post_status = 'draft' && post_type = 'post' ", 'ARRAY_N');

    $post_meta = get_post_meta((int)$id[0], $customFieldName);

    return $post_meta[0];
}

The function get_post_meta has the following signature get_post_meta ( int $post_id, string $key = '', bool $single = false ). The return value will be an array if $single is false. Will be value of meta data field if $single is true.

Try this:

function get_custom_field_for_current_user( $customFieldName ) {

    $current_user = wp_get_current_user();          
    global $wpdb;
    $id = $wpdb->get_row("SELECT ID FROM wp_posts WHERE post_title = '" . $current_user->user_login . "' && post_status = 'draft' && post_type = 'post' ", 'ARRAY_N');

    return get_post_meta((int)$id[0], $customFieldName, true);
                                                      //^ Here to return single value
}
