MongoClient::setWriteConcern — Set the write concern for this connection
This extension that defines this method is deprecated. Instead, the MongoDB extension should be used. There is no equivalent for this method in the new extension.
wThe write concern. This may be an integer denoting the number of servers required to acknowledge the write, or a string mode (e.g. "majority").
wtimeoutThe maximum number of milliseconds to wait for the server to satisfy the write concern.
Returns true on success, or false otherwise.
Emits E_WARNING if the w parameter is not an integer or string value.
Example #1 MongoClient::setWriteConcern() example
<?php
$mc = new MongoClient('mongodb://rs1.example.com,rs2.example.com');
// Require that the majority of servers in the replica set acknowledge writes
// within three seconds.
$mc->setWriteConcern('majority', 3000);
?>
