$unset not properly work on multiple field? about mongo-php-library

[jmikola]

The syntax you have looks correct. Note that the value of the fields in the $unset document are not relevant. Only the keys are used to discern the field names.

<?php

require __DIR__ . '/../vendor/autoload.php';

use MongoDB\BSON\UTCDateTime;
use MongoDB\Client;

$client = new Client('mongodb://localhost:27070/?replicaSet=rs0');

$coll = $client->selectCollection('test', 'coll');
$coll->drop();
$coll->insertOne([
    'owner_user_code' => 1,
    'membership_active_time' => 100,
    'membership_renewal_time' => new UTCDateTime(),
    'membership_start_date' => new UTCDateTime(),
    'membership_type' => 'foo',
    'metadata' => ['x' => 1],
    'vendor_payment' => 'bar',
]);

var_dump($coll->findOne());

$updateResult = $coll->updateOne(
    ['owner_user_code' => 1],
    ['$unset' => [
        'membership_active_time' => true,
        'membership_renewal_time' => true,
        'membership_start_date' => true,
        'membership_type' => true,
        'metadata' => true,
        'vendor_payment' => true,
    ]],
);

printf(
    "\nupdateOne matched %d and modified %d\n\n",
    $updateResult->getMatchedCount(),
    $updateResult->getModifiedCount(),
);

var_dump($coll->findOne());

Output:
