Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Dump first result set array(1) {
["A"]=>
string(1) "A"
}
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"
}
bool(false)
Try for a fourth result set bool(false)
