You could do it reading back to front the way you propose but I think it
will work much better in a proper for loop.
// the number of elements in the array.
$num_lines = count($file);
// the line we want to start the loop at.
if ($num_lines > 10)
$start_line = $num_lines - 10;
else
$start_line = 0;
// loop through the array
for ($i=$start_line; $i<$num_lines; $i++)
{
echo "Line #$i.\n";
//do your work here..
}
Hope that helps. Also please don't spam the list. Check your email program
make sure you're sending out only one copy.
