How can I add 90 days to a date: like add 90 days to 7/23/2004 which is pulled from a text file?

You first want to get the unix timestamp from the date as doing this
will make this a simple matter of addition.  Using mktime() is another
option.
Since the format you speak of is pretty common, let's do this:
<?php
  $date = '7/23/2004';
  $timestamp_current = strtotime($date);
  $timestamp_future  = $timestamp_current + (60*60*24*90);
  // The following will print 10/21/2004
  echo date('n/j/Y', $timestamp_future);
?>
