2、Mongodb驱动介绍

参考官方文档
Mongodb的php驱动是包含两个组件：

- PHP扩展-mongodb ([https://www.php.net/mongodb](https://www.php.net/mongodb))：提供低级API，主要用于将libmongoc和libbson与PHP集成。  
- PHP库 [https://www.mongodb.com/docs/php-library/current/](https://www.mongodb.com/docs/php-library/current/)：提供高级API，并且与其他MongoDB语言驱动一致。

PHP扩展提供了一个有限的API来连接数据库和执行通用命令、查询和写操作。
PHP库提供了一个功能齐全的API和模型客户端、数据库和集合对象。例如，MongoDB\Collection实现了在集合上执行CRUD操作和管理索引的方法。PHP库的API与MongoDB shell(https://blog.csdn.net/penngo/article/details/124232016)的API操作相似.

2.1、MongoDB版本的兼容性

3、安装驱动

使用MongoDB的PHP库前，需要先安装PHP扩展。

3.1、安装mongodb扩展

Linux、Unix和macOS用户可以使用PECL安装扩展(推荐)，也可以手动从源代码编译扩展。 下面的命令可以用于使用PECL安装扩展:

sudo pecl install mongodb

安装完扩展，需要在php.ini文件中添加:

extension=mongodb.so

Windows用户可以从PECL(https://pecl.php.net/package/mongodb)下载预编译的二进制文件,将php_mongodb.dll文件解压缩到PHP的扩展目录后，在PHP.ini文件中添加以下行:

extension=php_mongodb.dll

3.2、MongoDB驱动mongodb扩展CRUD操作

连接 MongoDB 语法如下：

参考：https://www.php.net/manual/zh/class.mongodb-driver-manager.php

3.2.1、插入、修改、删除操作，使用MongoDB\Driver\BulkWrite

$bulk = new MongoDB\Driver\BulkWrite(['ordered' => true]);
$bulk->delete([]);
$bulk->insert(['_id' => 1, 'x' => 1,'url'=>'https://21doc.net/']);
$bulk->insert(['_id' => 2, 'x' => 2,'url'=>'https://21doc.net/']);
$bulk->update(
    ['x' => 2],
    ['$set' => ['x' => 1]],
    ['limit' => 1, 'upsert' => false]
);
$bulk->delete(['x' => 1], ['limit' => 1]);
$bulk->update(
    ['_id' => 3],
    ['$set' => ['x' => 3]],
    ['limit' => 1, 'upsert' => true]
);

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$writeConcern = new MongoDB\Driver\WriteConcern(1);

try {
    $result = $manager->executeBulkWrite('db.collection', $bulk, $writeConcern);
} catch (MongoDB\Driver\Exception\BulkWriteException $e) {
    $result = $e->getWriteResult();

    // Check if the write concern could not be fulfilled
    if ($writeConcernError = $result->getWriteConcernError()) {
        printf("%s (%d): %s\n",
            $writeConcernError->getMessage(),
            $writeConcernError->getCode(),
            var_export($writeConcernError->getInfo(), true)
        );
    }

    // Check if any write operations did not complete at all
    foreach ($result->getWriteErrors() as $writeError) {
        printf("Operation#%d: %s (%d)\n",
            $writeError->getIndex(),
            $writeError->getMessage(),
            $writeError->getCode()
        );
    }
} catch (MongoDB\Driver\Exception\Exception $e) {
    printf("Other error: %s\n", $e->getMessage());
    exit;
}

printf("Inserted %d document(s)\n", $result->getInsertedCount());
printf("Updated  %d document(s)\n", $result->getModifiedCount());
printf("Upserted %d document(s)\n", $result->getUpsertedCount());
printf("Deleted  %d document(s)\n", $result->getDeletedCount());

?>

参考：https://www.php.net/manual/zh/class.mongodb-driver-bulkwrite.php

3.2.2、查询操作

/* Select only documents authord by "bjori" with at least 100 views */
$filter = [
    'author' => 'bjori',
    'views' => [
        '$gte' => 100,
    ],
];

$options = [
    /* Only return the following fields in the matching documents */
    'projection' => [
        'title' => 1,
        'article' => 1,
    ],
    /* Return the documents in descending order of views */
    'sort' => [
        'views' => -1
    ],
];

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

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$readPreference = new MongoDB\Driver\ReadPreference(MongoDB\Driver\ReadPreference::RP_PRIMARY);
$cursor = $manager->executeQuery('databaseName.collectionName', $query, $readPreference);

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

?>

参考：https://www.php.net/manual/zh/mongodb-driver-query.construct.php

3.3、安装MongoDB PHP库

推荐使用Composer安装，在项目根目录下运行命令:

composer require mongodb/mongodb    # 下载最新版本
composer require mongodb/mongodb^1.12.0 # 下载指定1.12.0版本

也可以从GitHub中下载mongo-php-library下载源码，但是不建议。

自动加载
需要项目中包含Composer的自动加载器。

require_once __DIR__ . '/vendor/autoload.php';

3.4、MongoDB PHP库CRUD操作，参考

3.4.1、插入一个文档

MongoDB\Collection::insertOne()方法将单个文档插入到MongoDB中，并返回一个MongoDB\InsertOneResult的实例，可以使用它来访问插入的文档的ID。

$collection = (new MongoDB\Client)->test->users;

$insertOneResult = $collection->insertOne([
    'username' => 'admin',
    'email' => '[email protected]',
    'name' => 'Admin User',
    'url'=>'https://21doc.net/'
]);

printf("Inserted %d document(s)\n", $insertOneResult->getInsertedCount());

var_dump($insertOneResult->getInsertedId());

3.4.2、插入多个文档

MongoDB\Collection::insertMany() 方法允许您在一个写操作中插入多个文档，并返回一个 MongoDB\InsertManyResult实例，可以使用它来访问插入文档的id。

$collection = (new MongoDB\Client)->test->users;

$insertManyResult = $collection->insertMany([
    [
        'username' => 'admin',
        'email' => '[email protected]',
        'name' => 'Admin User',
        'url'=>'https://21doc.net/'
    ],
    [
        'username' => 'test',
        'email' => '[email protected]',
        'name' => 'Test User',
        'url'=>'https://21doc.net/'
    ],
]);

printf("Inserted %d document(s)\n", $insertManyResult->getInsertedCount());

var_dump($insertManyResult->getInsertedIds());

3.4.3、查询文档

MongoDB PHP库提供了MongoDB\Collection::findOne()和MongoDB\Collection::find()方法用于查询文档，以及MongoDB\Collection::aggregate()方法用于执行聚合操作。

3.4.3.1、查询一个文档

$collection = (new MongoDB\Client)->test->zips;

$document = $collection->findOne(['_id' => '94301']);

var_dump($document);

参考：MongoDB\Collection::findOne()

3.4.3.2、查询多个文档

$collection = (new MongoDB\Client)->test->restaurants;

$cursor = $collection->find(
    [
        'cuisine' => 'Italian',
        'borough' => 'Manhattan',
    ],
    [
        'projection' => [
            'name' => 1,
            'borough' => 1,
            'cuisine' => 1,
        ],
        'limit' => 4,
    ]
);

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

参考：MongoDB\Collection::find()

3.4.3.3、正则查询

$collection = (new MongoDB\Client)->test->zips;

$cursor = $collection->find([
    'city' => new MongoDB\BSON\Regex('^garden', 'i'),
    'state' => 'TX',
]);

foreach ($cursor as $document) {
   printf("%s: %s, %s\n", $document['_id'], $document['city'], $document['state']);
}

参考：https://www.mongodb.com/docs/manual/reference/operator/query/regex/

3.4.3.4、聚合查询

$collection = (new MongoDB\Client)->test->zips;

$cursor = $collection->aggregate([
    ['$group' => ['_id' => '$state', 'count' => ['$sum' => 1]]],
    ['$sort' => ['count' => -1]],
    ['$limit' => 5],
]);

foreach ($cursor as $state) {
    printf("%s has %d zip codes\n", $state['_id'], $state['count']);
}

参考：MongoDB\Collection::aggregate()

3.4.4、更新文档

3.4.4.1、更新一个文档

使用MongoDB\Collection::updateOne()方法更新匹配过滤器的单个文档。 MongoDB\Collection::updateOne()返回一个MongoDB\UpdateResult对象，可以使用它来访问关于更新操作的统计信息。

$collection = (new MongoDB\Client)->test->users;
$collection->drop();

$collection->insertOne(['name' => 'Bob', 'state' => 'ny']);
$collection->insertOne(['name' => 'Alice', 'state' => 'ny']);
$updateResult = $collection->updateOne(
    ['state' => 'ny'],
    ['$set' => ['country' => 'us']]
);

printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
printf("Modified %d document(s)\n", $updateResult->getModifiedCount());

参考
MongoDB\Collection::updateOne()
MongoDB\Collection::findOneAndUpdate()

3.4.4.2、更新多个文档

MongoDB\Collection::updateMany()更新一个或多个匹配过滤条件的文档，并返回一个MongoDB\UpdateResult对象，可以使用它来访问关于更新操作的统计信息。

$collection = (new MongoDB\Client)->test->users;
$collection->drop();

$collection->insertOne(['name' => 'Bob', 'state' => 'ny', 'country' => 'us']);
$collection->insertOne(['name' => 'Alice', 'state' => 'ny']);
$collection->insertOne(['name' => 'Sam', 'state' => 'ny']);
$updateResult = $collection->updateMany(
    ['state' => 'ny'],
    ['$set' => ['country' => 'us']]
);

printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
printf("Modified %d document(s)\n", $updateResult->getModifiedCount());

参考：MongoDB\Collection::updateMany()

3.4.4.3、替换文档

MongoDB\Collection::replaceOne()方法替换匹配过滤条件的单个文档，并返回一个MongoDB\UpdateResult实例，可以使用它来访问关于替换操作的统计信息。

$collection = (new MongoDB\Client)->test->users;
$collection->drop();

$collection->insertOne(['name' => 'Bob', 'state' => 'ny']);
$updateResult = $collection->replaceOne(
    ['name' => 'Bob'],
    ['name' => 'Robert', 'state' => 'ca']
);

printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
printf("Modified %d document(s)\n", $updateResult->getModifiedCount());

参考：
MongoDB\Collection::replaceOne()
MongoDB\Collection::findOneAndReplace()

3.4.5、删除文档

3.4.5.1、删除一个文档

MongoDB\Collection::deleteOne()方法删除一个匹配过滤条件的文档，并返回一个MongoDB\DeleteResult，可以使用它来访问关于删除操作的统计信息。 The MongoDB\Collection::deleteOne() method deletes a single document that matches the filter criteria and returns a MongoDB\DeleteResult, which you can use to access statistics about the delete operation.

$collection = (new MongoDB\Client)->test->users;
$collection->drop();

$collection->insertOne(['name' => 'Bob', 'state' => 'ny']);
$collection->insertOne(['name' => 'Alice', 'state' => 'ny']);
$deleteResult = $collection->deleteOne(['state' => 'ny']);

printf("Deleted %d document(s)\n", $deleteResult->getDeletedCount());

3.4.5.2、删除多个文档

MongoDB\Collection::deleteMany()删除所有符合过滤条件的文档，并返回一个MongoDB\DeleteResult，可以使用它来访问关于删除操作的统计信息。

$collection = (new MongoDB\Client)->test->users;
$collection->drop();

$collection->insertOne(['name' => 'Bob', 'state' => 'ny']);
$collection->insertOne(['name' => 'Alice', 'state' => 'ny']);
