Question

我是MongoDB的新手，并在Windows上使用它。我创建了一个数据库，然后在那里创建了一个Collection并插入了记录，我正在通过GUI工具RoboMongo进行检查，它在GUI工具上显示，但是当我通过代码获取它时，它什么也没显示。以下是代码，请指导我做什么。

$m = new MongoClient('mongodb://root:root123@localhost');
$db = $m->selectDB('db_name');
$collection_name = 'collection_name';
$db->createCollection( $collection_name );
$get_collection = new MongoCollection( $db, $collection_name );
$data = array(
   '_id' => '1_record',
   'name' => 'Majid Ali',
   'designation' => 'Developer'
);
$get_collection->insert( $data );
$find = $get_collection->find();
print_r( $find );

你有任何错误吗？但我认为选择该系列的最佳方式是：

try{
    // Connecting to server
    $m = new MongoClient('mongodb://root:root123@localhost');
}catch(MongoConnectionException $connectionException){
    print $connectionException;
    exit;
}
try{
    // Getting MongoCollection

    $db = $m->db_name;
}catch(MongoException $mongoException){
    print $mongoException;
    exit;
}
$collection_name = 'collection_name';
$db->createCollection( $collection_name );

//Selected the Collection
$get_collection= $db->collection_name;

$data = array(
   '_id' => '1_record',
   'name' => 'Majid Ali',
   'designation' => 'Developer'
);
try{
    // Inserting data into students collection

    $get_collection->insert( $data );
}catch(MongoCursorException $mongoCursorException){
    echo $mongoCursorException;
    exit;
} 
$find = $get_collection->find();
$array = iterator_to_array($find );
print_r( $array  );

PHP MongoClient发现无法正常工作
