Example #1 MongoDB\Driver\ReadPreference::getMaxStalenessSeconds() example
<?php
$rp = new MongoDB\Driver\ReadPreference(MongoDB\Driver\ReadPreference::RP_SECONDARY);
var_dump($rp->getMaxStalenessSeconds());
$rp = new MongoDB\Driver\ReadPreference(MongoDB\Driver\ReadPreference::RP_SECONDARY, null, [
'maxStalenessSeconds' => MongoDB\Driver\ReadPreference::NO_MAX_STALENESS,
]);
var_dump($rp->getMaxStalenessSeconds());
$rp = new MongoDB\Driver\ReadPreference(MongoDB\Driver\ReadPreference::RP_SECONDARY, null, [
'maxStalenessSeconds' => MongoDB\Driver\ReadPreference::SMALLEST_MAX_STALENESS_SECONDS,
]);
var_dump($rp->getMaxStalenessSeconds());
$rp = new MongoDB\Driver\ReadPreference(MongoDB\Driver\ReadPreference::RP_SECONDARY, null, [
'maxStalenessSeconds' => 1000,
]);
var_dump($rp->getMaxStalenessSeconds());
?>
以上例程会输出：
int(-1) int(-1) int(90) int(1000)
