PDO::nextRowset() does not appear to be currently supported by the Firebird PDO driver. Unfortunate.
PDOStatement::nextRowset
(PHP 5 >= 5.1.0, PHP 7, PHP 8, PECL pdo >= 0.2.0)
PDOStatement::nextRowset — Advances to the next rowset in a multi-rowset statement handle
Description
public PDOStatement::nextRowset(): bool
Some database servers support stored procedures that return more than one rowset (also known as a result set). PDOStatement::nextRowset() enables you to access the second and subsequent rowsets associated with a PDOStatement object. Each rowset can have a different set of columns from the preceding rowset.
Parameters
This function has no parameters.
Return Values
Returns true on success or false on failure.
Examples
Example #1 Fetching multiple rowsets returned from a stored procedure
The following example shows how to call a stored procedure, MULTIPLE_ROWSETS, that returns three rowsets. We use a do / while loop to loop over the PDOStatement::nextRowset() method, which returns false and terminates the loop when no more rowsets can be returned.
<?php
$sql = 'CALL multiple_rowsets()';
$stmt = $conn->query($sql);
$i = 1;
do {
$rowset = $stmt->fetchAll(PDO::FETCH_NUM);
if ($rowset) {
printResultSet($rowset, $i);
}
$i++;
} while ($stmt->nextRowset());
function printResultSet(&$rowset, $i) {
print "Result set $i:\n";
foreach ($rowset as $row) {
foreach ($row as $col) {
print $col . "\t";
}
print "\n";
}
print "\n";
}
?>
The above example will output:
Result set 1: apple red banana yellow Result set 2: orange orange 150 banana yellow 175 Result set 3: lime green apple red banana yellow

When you call $stmt->nextRowset(); it returns TRUE every time and does not stop with FALSE even when no more results left.
It causes Fatal Error when calling
$results[] = $stmt->fetchAll(PDO::FETCH_ASSOC);
with error message
"PHP message: PHP Fatal error: Uncaught PDOException: SQLSTATE[HY000]: General error in ..."
unable to fetch result which not exists.
The desission is try {} catch(e) {}
$stmt = pdo->query("Call Get_multi_result();");
do {
try {
$streets[] = $stmt->fetchAll(PDO::FETCH_ASSOC);
} catch (PDOException $e) {
}
} while ($stmt->nextRowset());

on MSSQL and 'dsn' => 'dblib:...',:
If you know how many count rowset then don't use contruction of do..while.
<?php
do {
$pdoStatement->fetchAll(\PDO::FETCH_ASSOC);
} while (
$pdoStatement->nextRowset()
);
?>
When I get large fetchAll(over 30) for second nextRowset. I get error - Segmentation fault.
Uses step-by-step insted do..while is fix for this bug:
<?php
$pdoStatement->fetchAll(\PDO::FETCH_ASSOC);
$pdoStatement->nextRowset();
$pdoStatement->fetchAll(\PDO::FETCH_ASSOC);
?>

If you use PDO::fetch instead of PDO::fetchAll and do not reach the end the result set, PDO::nextRowset() will fail with "SQLSTATE[HY000]: General error: PDO_DBLIB: dbresults() returned FAIL."
