Handling of “Back to Home” population with PHP in WordPress

问题

I'm attempting to have a Title and URL populate based off the parent child relationship. I've been able to work with other developers here on Stackoverflow (ref: Echo the subtitle of a PARENT page within WordPress - Part (2)) to mimic a similar function based off of data gathered from tables, however, this will be static information that is populated.

What I need to be done:

If you are on the Homepage or using the "Default" template for the page, the Title will be "Homepage" and the URL will be "http://example.com". In this scenario the page id will be "0" for the homepage and any children will share this relationship based off of "0".

If you are on a Sub-brand homepage or a page using this template, the Title will be "Sub-brand" and the URL will be "http://example.com/sub". In this scenario the homepage id will be "67" and any children will share this relationship based off of "67".

Current version of the function:

<?php 
    if ($post->post_parent!=67) {
        // Sub-brand - children
        echo = "Sub brand child";
        $title .= "Sub-brand";
        $link .= "\nhttp://example.com/sub";
    } elseif($post->ID==0||count(get_pages('child_of='.$post->ID))!=67) {
        // Sub-brand - home
        echo = "Sub brand home";
        $title .= "Sub-brand";
        $link .= "\nhttp://example.com/sub";
    } else {
        // Homepage and children
        echo = "Everything else";
        $title .= "Homepage";
        $link .= "\nhttp://example.com/";
    }
?>

Current issue(s):

The homepage is being categorized under the initial "if" statement instead of "else"
The child pages that are using the "Homepage" as the parent are being associated with the "elseif" statement instead of "else"

What's working:

The Sub-brand homepage is properly being populated by the initial "if" statement
The child pages that use "Sub-brand" as the parent are being associated with the "elseif" statement

Any help would be appreciated with getting the associations correct. Be aware, I've been working with PHP for less than a week and I'm learning as I go.
