Studio 3T 破解教程：

一、建立文件studio3t.bat

@echo off
ECHO 重置Studio 3T的使用日期......
FOR /f "tokens=1,2,* " %%i IN ('reg query "HKEY_CURRENT_USER\Software\JavaSoft\Prefs\3t\mongochef\enterprise" ^| find /V "installation" ^| find /V "HKEY"') DO ECHO yes | reg add "HKEY_CURRENT_USER\Software\JavaSoft\Prefs\3t\mongochef\enterprise" /v %%i /t REG_SZ /d ""
ECHO 重置完成, 按任意键退出......
pause>nul
exit

二、将文件studio3t.bat文件移动到以下路径中

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp

三、双击运行

而后运行studio 3t软件

4、PHP操做mongodb

SQL查询语句 Mongo查询语句
CREATE TABLE USERS (a Number, b Number) 隐式的建立，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',
    ]
];

一、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

二、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

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

c、条件查询

//条件查询
//一、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);
}

//二、$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);
}

//三、$all：匹配多个值中全部值（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);//空
}

//三、$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);
}

//四、$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

//五、$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

//六、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，忽略大小写差别

d、汇集查询 

//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 = $collection->aggregate([
    [//过滤条件：只对符合条件的原始文档进行聚合运算，如果放在'$group'以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
        ]
    ],
    //如下操做如果放在'$group'以前则在聚合前做用于原始文档，若放在'$group'以后则在聚合后做用于结果文档
    ['$unwind' => '$E-Mail'],//将包含有某个数组类型字段的文档拆分红多个文档，每一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，能够对字段进行重命名，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 ] ]);

三、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做
$res = $collection->update(['First Name' => 'Yang'], ['$rename' => ['Hobby' => 'hobby', 'Age' => 'age']]);
//注意：若是文档中已经使用了指定名称的字段，则该字段将会被删除，而后再进行重命名操做。

//$setOnInsert：设置了upsert为true，而且发生了插入操做的时候，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（做用于数组字段），若字段不存在会先建立字段，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（做用于数组字段），若字段不存在会先建立字段，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（做用于数组字段），若字段不存在会先建立字段，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：删除数组中全部指定值
$res = $collection->update(['First Name' => 'Yang'], ['$pull' => ['E-Mail' => '123123@qq.com']]);

//$pullAll：删除数组中多个元素的全部值
$res = $collection->update(['First Name' => 'Yang'], ['$pullAll' => ['E-Mail' => ['123123@qq.com', '666@qq.com']]]);

//save()
//参数1：但愿保存的信息数组
//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，更新操做将不会获得确认；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做
//  j：默认为false，若设置为true，数据将在更新结果返回以前写入到日志中。
//  wtimeout：默认为10000（毫秒），用于指定服务器等待接收确认的时间
//  timeout：指定客户端须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表示操做成功，$res['updatedExisting']=1表示更新，$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，指定但愿返回的字段
//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做
//  new：默认为false，若设置为true则返回更新后的文档，不然返回更新前的文档
//  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']]);

四、删除

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

 5、PHP7以上操做Mongodb

一、查询

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

二、添加

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

三、修改

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

四、删除

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