TalkPHP - View Single Post - Can an included file 'know' where it's been included?

I'll make this as a new post, but I think I've cracked it, if I understand your question correctly -- which I think I do now. It will also work when includes have been daisy-chained.

php Code:

function getIncludedParent()
{
    $aIncluded = get_included_files();
    $iKey = array_search(__FILE__, $aIncluded);
    
    if(!array_key_exists($iKey - 1, $aIncluded))
    {
        return __FILE__;
    }
    
    return $aIncluded[$iKey - 1];
}

echo 'Included parent: ' . getIncludedParent();
