Beispiele
Beispiel #1 MongoDB\Driver\Manager::getServers() example
<?php
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
/* The driver connects to the database server lazily, so Manager::getServers()
* may initially return an empty array. */
var_dump($manager->getServers());
$command = new MongoDB\Driver\Command(['ping' => 1]);
$manager->executeCommand('db', $command);
var_dump($manager->getServers());
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
array(0) { } array(1) { [0]=> object(MongoDB\Driver\Server)#3 (10) { ["host"]=> string(9) "localhost" ["port"]=> int(27017) ["type"]=> int(1) ["is_primary"]=> bool(false) ["is_secondary"]=> bool(false) ["is_arbiter"]=> bool(false) ["is_hidden"]=> bool(false) ["is_passive"]=> bool(false) ["last_hello_response"]=> array(8) { ["isWritablePrimary"]=> bool(true) ["maxBsonObjectSize"]=> int(16777216) ["maxMessageSizeBytes"]=> int(48000000) ["maxWriteBatchSize"]=> int(1000) ["localTime"]=> object(MongoDB\BSON\UTCDateTime)#4 (1) { ["milliseconds"]=> int(1447267964517) } ["maxWireVersion"]=> int(3) ["minWireVersion"]=> int(0) ["ok"]=> float(1) } ["round_trip_time"]=> int(554) } }
