    C:ProgramDataMicrosoftWindowsStart MenuProgramsStartUp

    3、双击运行

    然后运行studio 3t软件

    四、PHP操作mongodb

    SQL查询语句Mongo查询语句
    CREATE TABLE USERS (a Number, b Number) 隐式的创建,或 MongoDB::createCollection().
    INSERT INTO USERS VALUES(1,1) $db->users->insert(array("a" => 1, "b" => 1));
    SELECT a,b FROM users $db->users->find(array(), array("a" => 1, "b" => 1));
    SELECT * FROM users WHERE age=33 $db->users->find(array("age" => 33));
    SELECT a,b FROM users WHERE age=33 $db->users->find(array("age" => 33), array("a" => 1, "b" => 1));
    SELECT a,b FROM users WHERE age=33 ORDER BY name $db->users->find(array("age" => 33), array("a" => 1, "b" => 1))->sort(array("name" => 1));
    SELECT * FROM users WHERE age>33 $db->users->find(array("age" => array('$gt' => 33)));
    SELECT * FROM users WHERE age<33 $db->users->find(array("age" => array('$lt' => 33)));
    SELECT * FROM users WHERE name LIKE "%Joe%" $db->users->find(array("name" => new MongoRegex("/Joe/")));
    SELECT * FROM users WHERE name LIKE "Joe%" $db->users->find(array("name" => new MongoRegex("/^Joe/")));
    SELECT * FROM users WHERE age>33 AND age<=40 $db->users->find(array("age" => array('$gt' => 33, '$lte' => 40)));
    SELECT * FROM users ORDER BY name DESC $db->users->find()->sort(array("name" => -1));
    CREATE INDEX myindexname ON users(name) $db->users->ensureIndex(array("name" => 1));
    CREATE INDEX myindexname ON users(name,ts DESC) $db->users->ensureIndex(array("name" => 1, "ts" => -1));
    SELECT * FROM users WHERE a=1 and b='q' $db->users->find(array("a" => 1, "b" => "q"));
    SELECT * FROM users LIMIT 20, 10 $db->users->find()->limit(10)->skip(20);
    SELECT * FROM users WHERE a=1 or b=2 $db->users->find(array('$or' => array(array("a" => 1), array("b" => 2))));
    SELECT * FROM users LIMIT 1 $db->users->find()->limit(1);
    EXPLAIN SELECT * FROM users WHERE z=3 $db->users->find(array("z" => 3))->explain()
    SELECT DISTINCT last_name FROM users $db->command(array("distinct" => "users", "key" => "last_name"));
    SELECT COUNT(*y) FROM users $db->users->count();
    SELECT COUNT(*y) FROM users where AGE > 30 $db->users->find(array("age" => array('$gt' => 30)))->count();
    SELECT COUNT(AGE) from users $db->users->find(array("age" => array('$exists' => true)))->count();
    UPDATE users SET a=1 WHERE b='q' $db->users->update(array("b" => "q"), array('$set' => array("a" => 1)));
    UPDATE users SET a=a+2 WHERE b='q' $db->users->update(array("b" => "q"), array('$inc' => array("a" => 2)));
    DELETE FROM users WHERE z="abc" $db->users->remove(array("z" => "abc"));
    $doc = [//定义一个文档,即一个数组
        'First Name' => 'Yang',
        'Last Name' => 'Yang',
        'Age' => 21,
        'Phone' => '110',
        'Address' => [
            'Country' => 'China',
            'City' => 'Shen Zhen'
        ],
        'E-Mail' => [
            '123456@qq.com',
        ]
    ];

    1、插入数据

    $mongo = new MongoClient('mongodb://localhost:27017');
    //选择数据库
    $db = $mongo->selectDB("test");
    //选择集合
    $collection = $db->selectCollection("admin");
    
    //新增
    $res = $collection->insert(array("name" => "yangs"));
    var_dump($res); //array(4) { ["n"]=> int(0) ["ok"]=> float(1)  插入成功

    2、查询数据

    a、查询单个数据

    $data = $collection->findOne(array("name" => "yangs"));
    var_dump($data); //array(4) { ["_id"]=> object(MongoId)#6 (1) { ["$id"]=> string(24) "5d5f9f51146e638c0600002c" } ["name"]=> string(5) "yangs" ["age"]=> int(18) ["like"]=> array(2) { [0]=> string(9) "玩游戏" [1]=> string(9) "打篮球" } }

      b、查询多个数据

    //查询所有
    $data = $collection->find();
    foreach ($data as $k => $v) {
        var_dump($v);
    }

    c、条件查询

    //条件查询
    //1、mongodb分别使用$lt、$lte、$eq、$gte、$gt、$ne表示<、<=、=、>=、>、<>,用于整数字段查询
    $cursor = $collection->find(array("age" =>array('$gt' =>10)));
    while ($doc = $cursor->getNext()){
        var_dump($doc);
    }
    
    //2、$in:匹配多个值中任意一个
    $cursor = $collection->find(array("Address.Country" => array('$in' => array("China", "USA"))));
    while ($doc = $cursor->getNext()){
        var_dump($doc);
    }
    
    //3、$all:匹配多个值中所有值(用于数组字段查询)
    $cursor = $collection->find(array("E-Mail" => array('$all' => array("123456@qq.com", "abc@qq.com"))));
    while ($doc = $cursor->getNext()){
        var_dump($doc);//
    }
    
    //3、$or:或查询
    $cursor = $collection->find(array('$or'=>array(array("Address.Country" => "China"), array("Address.Country" => "USA"))));
    while ($doc = $cursor->getNext()){
        var_dump($doc);
    }
    
    //4、$slice:获取数组字段中指定数目的元素,位于find()函数第二个参数中
    $cursor = $collection->find(['First Name' => 'Yang'], ['E-Mail' => ['$slice' => 2]]);//只返回前两个email
    $cursor = $collection->find(['First Name' => 'Yang'], ['E-Mail' => ['$slice' => -2]]);//只返回最后两个email
    $cursor = $collection->find(['First Name' => 'Yang'], ['E-Mail' => ['$slice' => [1, 2]]]);//忽略第一个,返回接下来两个
    
    //5、$exists:根据某个字段是否有设置值进行查询
    $cursor = $collection->find(['Hobby' => ['$exists' => false]]);//查找Hobby字段未设置值的文档
    
    //6、正则表达式查询
    $cursor = $collection->find(['First Name' => new MongoRegex('/^Ya/i')]);//查找First Name字段以Ya开头的文档,忽略大小写差异

    d、聚集查询 

    //聚合查询
    $data = $collection->aggregate(array(
        '$group' => array(
            "_id" => "Address.Country",
            "total" => array('$sum' => 1),//求总和,表示每匹配一个文档总和就加1
            "minAge" => array('$min' => '$Age'), //分组中Age字段最小值
        )
    ), [ "cursor" => [ "batchSize" => 0 ] ]);
    
    $res = $collection->aggregate([
        [//过滤条件:只对符合条件的原始文档进行聚合运算,若是放在'$group'之后则是只返回符合条件的结果文档
            '$match' => ['Age' => ['$gt' => 30]]
        ],
        [//指定分组字段、统计字段
            '$group' => [
                '_id' => '$Address.Country',
                'totalAge' => ['$sum' => '$Age']//计算各个分组Age字段总和
            ]
        ],
        //以下操作若是放在'$group'之前则在聚合前作用于原始文档,若放在'$group'之后则在聚合后作用于结果文档
        ['$unwind' => '$E-Mail'],//将包含有某个数组类型字段的文档拆分成多个文档,每个文档的同名字段的值为数组中的一个值。
        ['$project' => ['myAge' => '$Age', 'First Name' => '$First Name']],//指定返回字段,可以对字段进行重命名,格式:返回字段名 => $原来字段名
        ['$skip' => 2],//跳过指定数量的文档
        ['$limit' => 2],//只返回指定数量的文档
        ['$sort' => ['totalAge' => 1]]//排序
    ], [ "cursor" => [ "batchSize" => 0 ] ]);

    3、修改

    //$set:重置特定键的值,若字段不存在则新建字段并赋值
    $res = $collection->update(['First Name' => 'Yang'], ['$set' => ['Hobby' => 'pingpong']]);
    
    //$unset:删除字段
    $res = $collection->update(['First Name' => 'Yang'], ['$unset' => ['Hobby' => 1]]);
    
    //$rename:重命名字段,若字段不存在则不进行任何操作
    $res = $collection->update(['First Name' => 'Yang'], ['$rename' => ['Hobby' => 'hobby', 'Age' => 'age']]);
    //注意:如果文档中已经使用了指定名称的字段,则该字段将会被删除,然后再进行重命名操作。
    
    //$setOnInsert:设置了upsert为true,并且发生了插入操作的时候,将某个字段设置为特定的
    $res = $collection->update(['First Name' => 'Yang'], ['$setOnInsert' => ['lang' => 'English']], ['upsert' => true]);
    
    //$push:向指定字段添加一个值(作用于数组字段),若字段不存在会先创建字段,若字段值不是数组会报错
    $res = $collection->update(['First Name' => 'Yang'], ['$push' => ['E-Mail' => '123123@qq.com']]);
    
    //$push:向指定字段添加多个值(作用于数组字段),若字段不存在会先创建字段,若字段值不是数组会报错
    $res = $collection->update(['First Name' => 'Yang'], ['$pushAll' => ['E-Mail' => ['666@qq.com', '8888888@qq.com']]]);
    
    //使用$push和$each向某个字段添加多个值(作用于数组字段),若字段不存在会先创建字段,若字段值不是数组会报错
    $res = $collection->update(['First Name' => 'Yang'], ['$push' => ['E-Mail' => ['$each' => ['123123@qq.com', '666@qq.com']]]]);
    
    //$addToSet:将数据添加到数组中(只在目标数组没有该数据的时候才将数据添加到数组中)
    $res = $collection->update(['First Name' => 'Yang'], ['$addToSet' => ['E-Mail' => '123123@qq.com']]);
    $res = $collection->update(['First Name' => 'Yang'], ['$addToSet' => ['E-Mail' => ['$each' => ['123123@qq.com', '666@qq.com']]]]);
    
    //$pop:从数组中删除一个元素,-1表示删除第一个元素,1表示删除最后一个元素(其实负数都删除第一个元素,0或正数都删除最后一个元素)
    $res = $collection->update(['First Name' => 'Yang'], ['$pop' => ['E-Mail' => 1]]);
    
    //$pull:删除数组中所有指定值
    $res = $collection->update(['First Name' => 'Yang'], ['$pull' => ['E-Mail' => '123123@qq.com']]);
    
    //$pullAll:删除数组中多个元素的所有值
    $res = $collection->update(['First Name' => 'Yang'], ['$pullAll' => ['E-Mail' => ['123123@qq.com', '666@qq.com']]]);
    
    //save()
    //参数1:希望保存的信息数组
    //参数2:扩展选项
    //  fsync:若设置为true,w参数将被覆盖为0,数据将在更新结果返回前同步到磁盘。
    //  w:默认为1;若设置为0,更新操作将不会得到确认;使用复制集时可设置为n,确保主服务器在将修改复制到n个节点后才确认该更新操作
    //  j:默认为false,若设置为true,数据将在更新结果返回之前写入到日志中。
    //  wtimeout:默认为10000(毫秒),用于指定服务器等待接收确认的时间
    //  timeout:指定客户端需要等待服务器响应的超时时间(毫秒)
    //注意:若已存在则更新,若不存在则插入;更新时使用参数1指定的信息数组替换整个文档。
    //若想更新则应该在参数1中指定_id键的值。
    $doc = [//定义一个文档,即一个数组
        'First Name' => 'y',
        'Last Name' => 'y',
        'Age' => 18,
        'Phone' => '112',
        'Address' => [
            'Country' => 'China',
            'City' => '成都'
        ],
        'E-Mail' => [
            'abc@qq.com',
        ]
    ];
    //$res['ok']=1表示操作成功,$res['updatedExisting']=1表示更新,$res['upserted']=1表示插入
    $res = $collection->save($doc);
    
    //findAndModify()
    //参数1:指定查询条件
    //参数2:指定用于更新文档的信息
    //参数3:可选,指定希望返回的字段
    //参数4:扩展选项
    //  sort:以特定顺序对匹配文档进行排序
    //  remove:若设置为true,第一个匹配文档将被删除
    //  update:若设置为true,将在被选择的文档上执行更新操作
    //  new:默认为false,若设置为true则返回更新后的文档,否则返回更新前的文档
    //  upsert:若设置为true,没有找到匹配文档的时候将插入一个新的文档
    $res = $collection->findAndModify(['First Name' => 'y'], ['$push' => ['E-Mail' => '123@qq.com']]);

    4、删除

    $res = $collection->remove(array("name" => "admin"));//$res['n']表示删除了几个文档

     五、PHP7以上操作Mongodb

    1、查询

    $manager = new MongoDBDriverManager('mongodb://localhost:27017');
    $query = new MongoDBDriverQuery(['age' => 24], ['sort' => ['age' => 1]]);
    $cursor = $manager->executeQuery('wjt.friend', $query);
     
    $data = [];
    foreach($cursor as $doc) {
        $data[] = $doc;
    }

    2、添加

    $manager = new MongoDBDriverManager('mongodb://localhost:27017');
    $bulk = new MongoDBDriverBulkWrite;
    $bulk->insert(['name' => 'JetWu5', 'age' => 26]);
    $bulk->insert(['name' => 'JetWu6', 'age' => 26]);
     
    $writeConcern = new MongoDBDriverWriteConcern(MongoDBDriverWriteConcern::MAJORITY, 1000);//可选,修改确认
    $res = $manager->executeBulkWrite('wjt.friend', $bulk, $writeConcern);

    3、修改

    $manager = new MongoDBDriverManager('mongodb://localhost:27017');
    $bulk = new MongoDBDriverBulkWrite;
    $bulk->update(
        ['name' => 'JetWu5'],
        ['$set' => ['age' => 30, 'promise' => 'always smile!']]
    );
    $writeConcern = new MongoDBDriverWriteConcern(MongoDBDriverWriteConcern::MAJORITY, 1000);//可选,修改确认
    $res = $manager->executeBulkWrite('wjt.friend', $bulk, $writeConcern);
    echo '<pre>';
    print_r($res);

    4、删除

    $manager = new MongoDBDriverManager('mongodb://localhost:27017');
    $bulk = new MongoDBDriverBulkWrite;
    $bulk->delete(['name' => 'JetWu3']);
    $bulk->delete(['name' => 'JetWu4']);
    $writeConcern = new MongoDBDriverWriteConcern(MongoDBDriverWriteConcern::MAJORITY, 1000);//可选,修改确认
    $res = $manager->executeBulkWrite('wjt.friend', $bulk, $writeConcern);
    echo '<pre>';
    print_r($res);
