Thanks, That does get me closer and explains why I was getting no results
from

$aKeys = array_keys($Buf,("chuck"));
print_r ($aKeys);

I wrote that snippet just to see what the output was from array_keys because
nothing was working as expected.
What I was aiming for is an array with all of the keys for <HR> in a text
file
in order to trim the file to the last X number of occurrences of <HR>.
