PHP7 操作 MongoDB-KeepStudy

PHP7 操作 MongoDB

#### PHP7 Mongdb 扩展安装
```shell
$ /usr/local/php7/bin/pecl install mongodb
```
>使用pecl命令来安装MongoDB只适合PHP7+。

执行成功后，在 php.ini 文件，添加 extension=mongodb.so 配置
可以直接执行以下命令来添加：
```shell
$ echo "extension=mongodb.so" >> `/usr/local/php7/bin/php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`
```

####操作实例

```php
<?php
#连接MongoDB 
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

##========》插入数据
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1, 'name'=>'W3Cschool教程', 'url' => 'http://www.w3cschool.com']);
$bulk->insert(['x' => 2, 'name'=>'Google', 'url' => 'http://www.google.com']);
$bulk->insert(['x' => 3, 'name'=>'taobao', 'url' => 'http://www.taobao.com']);
$manager->executeBulkWrite('test.sites', $bulk);

##========》查询数据
$filter = ['x' => ['$gt' => 1]];
$options = [
    'projection' => ['_id' => 0],
    'sort' => ['x' => -1],
];
$query = new MongoDB\Driver\Query($filter, $options);
$cursor = $manager->executeQuery('test.sites', $query);
foreach ($cursor as $document) {
    print_r($document);
}

##========》更新数据
$bulk->update(
    ['x' => 2],
    ['$set' => ['name' => 'w3cschool在线工具', 'url' => '123.w3cschool.cn/webtools']],
    ['multi' => false, 'upsert' => false]
);
$result = $manager->executeBulkWrite('test.sites', $bulk);

##========》删除数据

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