PHP7操作MongoDB

目錄

• 插入數據
• 查詢數據
• 更新數據
• 刪除數據

PHP7裡面使用如下庫，操作比較複雜

PHP7連接MongoDB語法如下：

//參數規則: mongodb://賬號:密碼@IP:埠/資料庫
$manager = new \MongoDB\Driver\Manager("mongodb://php:123456@localhost:27017/php");

插入數據

//1.連接MongoDB
$manager = new \MongoDB\Driver\Manager("mongodb://php:123456@localhost:27017/php");

//2.創建一個BulkWrite對象
$bulk = new \MongoDB\Driver\BulkWrite();
$bulk->insert(['name' => 'bashlog', 'age' => 26, 'email' => '[email protected]']);
$bulk->insert(['name' => 'itbsl', 'age' => 12, 'email' => '[email protected]']);

//3.執行插入
$manager->executeBulkWrite('php.stu', $bulk);

查看插入情況

查詢數據

//1.連接MongoDB
$manager = new \MongoDB\Driver\Manager("mongodb://php:123456@localhost:27017/php");

//2.創建一個Query對象
$filter = ['age' => ['$gt' => 5]];
$options = [
    'sort' => ['age' => -1]
];
$query = new \MongoDB\Driver\Query($filter, $options);
$cursor = $manager->executeQuery('php.stu', $query);

foreach ($cursor as $document) {
    var_dump($document);
}

更新數據

//1.規則:mongodb://賬號:密碼@IP:埠/資料庫
$manager = new \MongoDB\Driver\Manager("mongodb://php:123456@localhost:27017/php");


//2.創建一個BulkWrite對象
$bulk = new \MongoDB\Driver\BulkWrite();

$bulk->update(
    ['age' => 12],
    ['$set' => ['name' => 'kitty', 'age' => 122]],
    ['multi' => false, 'upsert' => false]
);

$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);
$result = $manager->executeBulkWrite('php.stu', $bulk, $writeConcern);

刪除數據

//1.規則:mongodb://賬號:密碼@IP:埠/資料庫
$manager = new \MongoDB\Driver\Manager("mongodb://php:123456@localhost:27017/php");


//2.創建一個BulkWrite對象
$bulk = new \MongoDB\Driver\BulkWrite();
//limit為1時，刪除第一條匹配的數據
//limit為0時，刪除所有匹配數據
$bulk->delete(['age' => 122], ['limit' => 1]);

$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);
$result = $manager->executeBulkWrite('php.stu', $bulk, $writeConcern);
