// Before (this was repeated 3 times in one script, copy and pasted exactly...)
for($i=0,$btotal=0,$total=0,$page=1;$lclass=$row['class'],$lwhse=$row['whse'],$row=mysql_fetch_array($res);$i++,$total+=$row['cost'],$btotal+=$row['cost'],$gtotal+=$row['cost']) {
  // ...snip.. 35 lines of echo statements dumping HTML
}

// Removing all the unused variables reduced it down to:
for ($i = 0; $row = mysql_fetch_array($res); $i++) {
  // Same 35 lines of echo statements dumping HTML
}
// with $i only being used to count the number of records being returned.


// After further refactoring:
$data = $result->fetchAll(PDO::FETCH_ASSOC);
// Then pass $data off to a template and $i is no longer needed
