MongoClient::getWriteConcern — Get 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.
此函数没有参数。
This function returns an array describing the write concern. The array contains the values w for an integer acknowledgement level or string mode, and wtimeout denoting the maximum number of milliseconds to wait for the server to satisfy the write concern.
Example #1 MongoClient::getWriteConcern() return value example
<?php
$mc = new MongoClient('mongodb://localhost:27017', array('wTimeoutMS' => 500));
var_dump($mc->getWriteConcern());
$mc->setWriteConcern(1, 1000);
var_dump($mc->getWriteConcern());
?>
以上例程会输出：
array(2) {
["w"]=>
int(1)
["wtimeout"]=>
int(500)
}
array(2) {
["w"]=>
int(1)
["wtimeout"]=>
int(1000)
}
