The search in the array_keys if for searching in the keys and not the content
in the cells (there are plenty other functions for that).
The parentheses around chuck don't give you any advantage, drop those and get
a code that is easier to understand. Don't forget to use indentation and you
make the code even easier to read.
Not sure, but the following code may be more of use for you...
$Buf = file("bsshort2.txt");
foreach($Buf AS $key => $value) {
echo $key." => ".$value."\n";
if(!(stristr($value, '<HR>') === FALSE)) {
echo "there was a horizontal line on the {$key} line\n";
}
}
