function to delete older sqlite records when the limit is reached

I had an issue where a sqlite database was hitting over 100,000 records and this was causing quite a lot of lag and crashing on my server, the number of records was not really meant to be this high, so i can just keep a few thousand so it does not cause lag.

This is the function i added and run before or after the latest item is inserted to remove older items in the database. 

PHP

// this will delete records over the specified number if run.
// it will keep the latest $records_to_keep number and delete older ones.
public function delete_over($records_to_keep = 1000) {
  $db_table_name = $this->db_table_name;
  $sql = "DELETE FROM $db_table_name WHERE ROWID IN (SELECT ROWID FROM $db_table_name ORDER BY ROWID DESC LIMIT -1 OFFSET $records_to_keep)";
  $result = $this->db->query($sql);
}

// example run on keywords class
$keywords->delete_over($records_to_keep = 1000);

In this case my anchor this week becomes driving almost 2hrs outside of Atlanta to one of my favorite hard core gyms in the world.. MetroFlex aka The Dungeon. The gym owners turn the heat way up so it becomes a fun sweat box and the gym members just watch from afar and leave me alone. I happily drive myself long distances to find MY ANCHOR. Our anchor allows us to have balance, focus and be as productive as possible. And if you're in the middle of a heavy set and your headphones start to fall off your head, like mine did here.. well.. f*ck the headphones. Let em break and fall. You can always get a new pair, but the iron ain't ever gonna lift itself.
