Examples

Example #1 Partial result if at least one write is successful

<?php

$manager = new MongoDB\Driver\Manager;

$bulk = new MongoDB\Driver\BulkWriteCommand;
$bulk->deleteMany('db.coll', []);
$bulk->insertOne('db.coll', ['_id' => 1]);
$bulk->insertOne('db.coll', ['_id' => 1]);

try {
    $result = $manager->executeBulkWriteCommand($bulk);
} catch (MongoDB\Driver\Exception\BulkWriteCommandException $e) {
    $result = $e->getPartialResult();
}

var_dump($result?->getInsertedCount());

?>

The above example will output:

int(1)

Example #2 No partial result if no writes are successful

<?php

$manager = new MongoDB\Driver\Manager;

$bulk = new MongoDB\Driver\BulkWriteCommand;
$bulk->deleteMany('db.coll', []);
$bulk->insertOne('db.coll', ['_id' => 1]);
$manager->executeBulkWriteCommand($bulk);

$bulk = new MongoDB\Driver\BulkWriteCommand;
$bulk->insertOne('db.coll', ['_id' => 1]);

try {
    $result = $manager->executeBulkWriteCommand($bulk);
} catch (MongoDB\Driver\Exception\BulkWriteCommandException $e) {
    $result = $e->getPartialResult();
}

var_dump($result?->getInsertedCount());
