$a_Row1 = odbc_fetch_array($r_Results);

$a_Row2 = odbc_fetch_array($r_Results);

echo "Dump first result set";

var_dump($a_Row1, $a_Row2);



echo "Get second results set ";

var_dump(odbc_next_result($r_Results));



$a_Row1 = odbc_fetch_array($r_Results);

$a_Row2 = odbc_fetch_array($r_Results);

echo "Dump second result set ";

var_dump($a_Row1, $a_Row2);



echo "Get third results set ";

var_dump(odbc_next_result($r_Results));



$a_Row1 = odbc_fetch_array($r_Results);

$a_Row2 = odbc_fetch_array($r_Results);

echo "Dump third result set ";

var_dump($a_Row1, $a_Row2);



echo "Try for a fourth result set ";

var_dump(odbc_next_result($r_Results));

?>

The above example will output:

}
bool(false)
Get second results set bool(true)
Dump second result set array(1) {
  ["B"]=>
  string(1) "B"
}
bool(false)
Get third results set bool(true)
Dump third result set array(1) {
  ["C"]=>
  string(1) "C"
