This script appears to work quite well. It prints out every mammal
order, family, genus and species - and surprisingly rapidly. But the
display alternates data with the error message "Warning: Invalid
argument supplied for foreach() in C:\sites\freedomware\axis.php on line
127."

display_errors must be turned off in my head.

You want
if (isset($nodes[$parent])) {
....
}

around the foreach.
