    例

    例1 MongoDB\Driver\WriteResult::getWriteErrors() with a single error

    <?php

    $manager     = new MongoDB\Driver\Manager;


    $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());
    }

    ?>

    上の例の出力は、 たとえば以下のようになります。

    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 } }

    例2 MongoDB\Driver\WriteResult::getWriteErrors() with multiple errors

    <?php

    $manager     = new MongoDB\Driver\Manager;


    $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());
    }

    ?>

    上の例の出力は、 たとえば以下のようになります。

    array(2) { [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 } [1]=> object(MongoDB\Driver\WriteError)#6 (4) { ["message"]=> string(81) "E11000 duplicate key error collection: db.collection index: _id_ dup key: { : 4 }" ["code"]=> int(11000) ["index"]=> int(5) ["info"]=> NULL } }
