本文教程只在 PHP7 安装使用！！！

PHP7 Mongdb 扩展安装

我们使用 pecl 命令来安装：

$ /usr/local/php7/bin/pecl install mongodb

执行成功后，会输出以下结果：

……
Build process completed successfully
Installing '/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/mongodb.so'
install ok: channel://pecl.php.net/mongodb-1.1.7
configuration option "php_ini" is not set to php.ini location
You should add "extension=mongodb.so" to php.ini

接下来我们打开 php.ini 文件，添加 extension=mongodb.so 配置。

可以直接执行以下命令来添加。

$ echo "extension=mongodb.so" >> `/usr/local/php7/bin/php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`

注意：以上执行的命令中 php7 的安装目录为 /usr/local/php7/，如果你安装在其他目录，需要相应修改 pecl 与 php 命令的路径。

Mongodb 使用

PHP7 连接 MongoDB 语法如下：

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

插入数据

将 name 为"511遇见" 的数据插入到 test 数据库的 runoob 集合中。

```
<?php
```
```
$bulk = new MongoDB\Driver\BulkWrite;
```

$document = ['_id' => new MongoDB\BSON\ObjectID, 'name' => '511遇见'];

```
 
```
```
$_id= $bulk->insert($document);
```
```
 
```
```
var_dump($_id);
```
```
 
```

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

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

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

```
?>
```

读取数据

这里我们将三个网址数据插入到 test 数据库的 sites 集合，并读取迭代出来：

```
<?php
```

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

```
 
```
```
// 插入数据
```
```
$bulk = new MongoDB\Driver\BulkWrite;
```

$bulk->insert(['x' => 1, 'name'=>'511遇见', 'url' => 'http://www.511yj.com']);

$bulk->insert(['x' => 2, 'name'=>'baidu', 'url' => 'http://www.baidu.com']);

$bulk->insert(['x' => 3, 'name'=>'bing', 'url' => 'http://www.bing.com']);

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

```
 
```
```
$filter = ['x' => ['$gt' => 1]];
```
```
$options = [
```
```
    'projection' => ['_id' => 0],
```
```
    'sort' => ['x' => -1],
```
```
];
```
```
 
```
```
// 查询数据
```

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

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

```
 
```
```
foreach ($cursor as $document) {
```
```
    print_r($document);
```
```
}
```
```
?>
```

输出结果为：

stdClass Object
(
    [x] => 3
    [name] => bing
    [url] => http://www.bing.com
)
stdClass Object
(
    [x] => 2
    [name] => baidu
    [url] => http://www.baidu.com
)

更新数据

接下来我们将更新 test 数据库 sites 集合中 x 为 2 的数据：

```
<?php
```
```
$bulk = new MongoDB\Driver\BulkWrite;
```
```
$bulk->update(
```
```
    ['x' => 2],
```

    ['$set' => ['name' => '图像印记', 'url' => 'images.511yj.com']],

    ['multi' => false, 'upsert' => false]

```
);
```
```
 
```

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

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

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

```
?>
```

删除数据

以下实例删除了 x 为 1 和 x 为 2的数据，注意 limit 参数的区别：

```
<?php
```
```
$bulk = new MongoDB\Driver\BulkWrite;
```

$bulk->delete(['x' => 1], ['limit' => 1]);   // limit 为 1 时，删除第一条匹配数据

$bulk->delete(['x' => 2], ['limit' => 0]);   // limit 为 0 时，删除所有匹配数据

```
 
```

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

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

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

```
?>
```
