范例
Example #1 Catching MongoDuplicateKeyException
<?php$mc = new MongoClient("localhost");$c = $mc->selectCollection("test", "test");$c->insert(array('_id' => 1));try { $c->insert(array('_id' => 1));} catch (MongoWriteConcernException $e) { echo $e->getMessage(), "\n";}?>
以上例程的输出类似于：
localhost:27017: insertDocument :: caused by :: 11000 E11000 duplicate key error index: test.test.$_id_ dup key: { : 1 }
