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.
