This is my first php program!

Performance Tuning
Before thinking much about performance tuning, get your code working. Once you
have working code, you can then locate the slow bits. If you try to optimize your
code while writing it, you’ll discover that optimized code tends to be more difficult
to read and to take more time to write. If you spend that time on a section of code
that isn’t actually causing a problem, that’s time that was wasted, especially when it
comes time to maintain that code, and you can no longer read it.
Once you get your code working, you may find that it needs some optimization.
Optimizing code tends to fall within one of two areas: shortening execution times
and lessening memory requirements.

Results!

Here are the results of your search:

require_once('DB.php');
$db = DB::connect('mysql://gnat:waldus@localhost/webdb');
if (DB::iserror($db)) die($db->getMessage( ));
// ...
?>

Phone List

$dd = odbc_connect (PhoneListDSN, user, password);
// disable autocommit if we're confirming
if ($submit == "Add Listing") {
$start_trans = odbc_autocommit ($dd, 0);
}
// insert if we've got values submitted
if ($submit == "Add Listing" || $submit == "Confirm") {
$sql = "insert into phone_list ([extension],[name])";
$sql .= " values ('$ext_num', '$add_name')";
$result = odbc_exec($dd, $sql);
}
?>

// build table of extension and name values
$result = odbc_exec ($dd, "select * from phone_list");
$cols = array( );
$row = odbc_fetch_into($result, $cols);
while ($row) {
if ($cols[0] == $ext_num && $submit != "Confirm") {
?>
