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.

参数

wtimeout

The maximum number of milliseconds to wait for the server to satisfy the write concern.

返回值

Returns true on success, or false otherwise.

错误／异常

Emits E_WARNING if the w parameter is not an integer or string value.
