### TEST BEGINS

### CLEANUP

$db->Execute("delete from photos where id=9999");

### VALIDATION

if ($v !== $val) echo "<b>*** ERROR: Inserted value does not match downloaded val<b>";
else echo "<b>*** OK: Passed</b>";

echo "<pre>";
echo "INSERTED: ", $enc;
echo "<hr />";
echo"RETURNED: ", rawurlencode($v);
