RE: [PHP-DB] Functions - scope of returned result
To answer my own question again, I didn't assign the returned value from the
function call to a variable:
$piv_result=queries();
All OK.

One more bite on this code.
function queries(){
//code..
$piv_result=mysql_db_query($db, $query, $connection) or die (Query9
failed: $query);
return $piv_result;
}
function print(){
global $piv_result;
$count_fields=mysql_num_fields($piv_result); //ERROR:
//code...
}
//MAIN
queries();
print();
Should this work - $piv_result is being returned from one function and then
being used in another function. Am I missing something?

Yes, you're returning the result set, but you're not assigning it anywhere.
$rs = queries();
print($rs);
