  - by Alan Storm

  I'm looking for a list of built in PHP functions that a programmer could use to send an email.

  In PHP I'm running a mysql_query that has an ORDER BY clause. I'm then iterating through the results to build an associative array, with the row_id as the key.

When I iterate through that Javascript variable, will I still have the order that was returned from the mysql_query?
