發布時間：2019-09-29 16:34:25作者：wangjian瀏覽量：525點贊量：0

一：插入數據

例：向默認的test數據庫的wj表中插入數據$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

// 插入數據

$bulk = new MongoDB\Driver\BulkWrite;

$bulk->insert(['id' => 1, 'name'=>'測試', 'url' => 'http://www.百度.com']);

$manager->executeBulkWrite('test.wj', $bulk);

2：查詢數據

查詢test數據庫的wj表中name值不為測試的數據$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

$filter = ['name' => '測試'];

$options = [

'projection' => ['_id' => 0],

'sort' => ['name' => -1],

];

$query = new MongoDB\Driver\Query($filter, $options);

$cursor = $manager->executeQuery('test.wj', $query);

foreach ($cursor as $document) {

print_r($document);

}

3:更新數據

將test數據庫中的wj表中id為1的數據中name字段變為測試1234，$bulk = new MongoDB\Driver\BulkWrite;

$bulk->update(

['id' => 1],

['$set' => ['name' => '測試1234']],

['multi' => false, 'upsert' => false] ?#multi表示只更新一條數據，upsert表示如果不存在update的記錄，不進行插入操作

);

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);

$result = $manager->executeBulkWrite('test.wj', $bulk, $writeConcern);

4：刪除數據$bulk = new MongoDB\Driver\BulkWrite;

$bulk->delete(['id' => 1], ['limit' => 1]);? ?// limit 為 1 時，刪除第一條匹配數據

$bulk->delete(['id' => 2], ['limit' => 0]);? ?// limit 為 0 時，刪除所有匹配數據

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);

$result = $manager->executeBulkWrite('test.wj', $bulk, $writeConcern);
