Jason,

Here is my rendition of what you should do.

<?PHP

$SQL = "SELECT  areacode, prefix
        FROM    Test
        WHERE   `areacode` = '907'
        AND     `prefix` = '200'";

$result = mysql_query($SQL);

$values = '';

while( $row = mysql_fetch_assoc($result) ) {
  foreach ( range(0, 9999) AS $n ) {
    $values .= $row['areacode'] . '-' . $row['prefix'] . '-' .
               str_pad($n, 4, '0', STR_PAD_LEFT);
  }
}

echo $values;

?>

It will be much faster if you build the complete string in memory then echo out
the built string.
