Question

I have a MongoDB 2.2 replicaset setup (2 nodes), and connect to test using PHP, e.g.

$mongo = new Mongo("mongodb://192.168.1.1:27017,192.168.1.2:27017", 
                        array("replicaSet" => "testrs", 
                              "safe" => TRUE));
$db = $mongo->test;
$collection = $db->dump;

while (true) {

    echo "Result: " . 
            $collection->insert(array( "ts" => time() ));

    sleep(10);
}

During the middle of the execution, when I stepDown from the primary node, I found the insert stop working but the echo stil give me 1, so no exception was throw, any issue with my code above?

As you can read here, insert throws exceptions only when safe option is set:

Throws MongoCursorException if the “safe” option is set and the insert
fails. (Version 1.0.1+)

Throws MongoCursorTimeoutException if the “safe” option is set and the
operation takes longer than MongoCursor::$timeout milliseconds to
complete. This does not kill the operation on the server, it is a
client-side timeout.

Set safe option and you should be able to see the exception thrown.
