Exemplo #1 MongoDB\Driver\BulkWrite::__construct() example

<?php

$bulk 
= new MongoDB\Driver\BulkWrite(['ordered' => true]);
$bulk->delete([]);
$bulk->insert(['_id' => 1'x' => 1]);
$bulk->insert(['_id' => 2'x' => 2]);
$bulk->update(
    [
'x' => 2],
    [
'$set' => ['x' => 1]],
    [
'limit' => 1'upsert' => false]
);
$bulk->delete(['x' => 1], ['limit' => 1]);
$bulk->update(
    [
'_id' => 3],
    [
'$set' => ['x' => 3]],
    [
'limit' => 1'upsert' => true]
);

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$writeConcern = new MongoDB\Driver\WriteConcern(1);

try {
    
$result $manager->executeBulkWrite('db.collection'$bulk$writeConcern);
} catch (
MongoDB\Driver\Exception\BulkWriteException $e) {
    
$result $e->getWriteResult();

    
// Check if the write concern could not be fulfilled
    
if ($writeConcernError $result->getWriteConcernError()) {
        
printf("%s (%d): %s\n",
            
$writeConcernError->getMessage(),
            
$writeConcernError->getCode(),
            
var_export($writeConcernError->getInfo(), true)
        );
    }

    
// Check if any write operations did not complete at all
    
foreach ($result->getWriteErrors() as $writeError) {
        
printf("Operation#%d: %s (%d)\n",
            
$writeError->getIndex(),
            
$writeError->getMessage(),
            
$writeError->getCode()
        );
    }
} catch (
MongoDB\Driver\Exception\Exception $e) {
    
printf("Other error: %s\n"$e->getMessage());
    exit;
}

printf("Inserted %d document(s)\n"$result->getInsertedCount());
printf("Updated  %d document(s)\n"$result->getModifiedCount());
printf("Upserted %d document(s)\n"$result->getUpsertedCount());
printf("Deleted  %d document(s)\n"$result->getDeletedCount());

?>

O exemplo acima irá imprimir:

Inserted 2 document(s)
Updated  1 document(s)
Upserted 1 document(s)
