<?php

$manager 
= new MongoDB\Driver\Manager("mongodb://rs1.example.com,rs2.example.com/?replicaSet=myReplicaSet");

$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1]);

$writeConcern = new MongoDB\Driver\WriteConcern(21);

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

?>

  string(33) "waiting for replication timed out"
  ["code"]=>
  int(64)
  ["info"]=>
  object(stdClass)#7 (1) {
    ["wtimeout"]=>
    bool(true)
