Examples

Example #1 MongoDB\Driver\WriteResult::getWriteErrors with a single error

<?php

$manager = new MongoDB\Driver\Manager;

/* By default, bulk write operations are executed serially in order and
 * execution will stop after the first error.
 */
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['_id' => 1]);
$bulk->insert(['_id' => 2]);
$bulk->insert(['_id' => 2]);
$bulk->insert(['_id' => 3]);
$bulk->insert(['_id' => 4]);
$bulk->insert(['_id' => 4]);

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

?>

The above example will output something similar to:

array(1) {
  [0]=>
  object(MongoDB\Driver\WriteError)#5 (4) {
    ["message"]=>
    string(81) "E11000 duplicate key error collection: db.collection index: _id_ dup key: { : 2 }"
    ["code"]=>
    int(11000)
    ["index"]=>
    int(2)
    ["info"]=>
    NULL
  }
}

Example #2 MongoDB\Driver\WriteResult::getWriteErrors with multiple errors

<?php

$manager = new MongoDB\Driver\Manager;

/* The "ordered" option may be used to allow bulk write operations to continue
 * executing after the first error is encountered.
 */
$bulk = new MongoDB\Driver\BulkWrite(['ordered' => false]);
$bulk->insert(['_id' => 1]);
$bulk->insert(['_id' => 2]);
$bulk->insert(['_id' => 2]);
$bulk->insert(['_id' => 3]);
$bulk->insert(['_id' => 4]);
$bulk->insert(['_id' => 4]);

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

?>
