php mongodb findandmodify not working - php

Question

I am using php and mongodb. I want to use findandmodify. My field is { "_id" : ObjectId("58d37e612d4ffa498b99c2d4"), "userid" : "1234", "active_time" : "hai" }
I want to modify active_time. For example change the value "hai" to "1234"
I am using MongoDB\Driver\Manager.
try {
$mng = new MongoDB\Driver\Manager("mongodb://username:password#localhost:27017/db");
$userid = '1234';
$retval = $mng->findAndModify(
array("userid" => $userid), // searchQuery
array('$set' => array('active_time' => "kkk")) // UpdateQuery
);
$command = new MongoDB\Driver\Command($retval);
$cursor = $manager->executeCommand('db.online', $command);
} catch (MongoDB\Driver\Exception\Exception $e) {
$filename = basename(__FILE__);
echo "The $filename script has experienced an error.\n";
echo "It failed with the following exception:\n";
echo "Exception:", $e->getMessage(), "\n";
echo "In file:", $e->getFile(), "\n";
echo "On line:", $e->getLine(), "\n";
}
It shows the error is
Fatal error: Uncaught Error: Call to undefined method MongoDB\Driver\Manager::findAndModify()
in line
$retval = $mng->findAndModify(
array("userid" => $userid), // searchQuery
array('$set' => array('active_time' => "kkk")) // UpdateQuery
);
How it possible? please help me?

Answer 1

I got the answer. Change the findAndModify to update. The modified code is shown below.
$bulk->update(
array("userid" => '1234'), // searchQuery
array('$set' => array('active_time' => "kkk")) // UpdateQuery
);
$mng->executeBulkWrite("browser.online", $bulk);
if(!empty($mng)) {
echo "success";
} else {
echo "not";
}
