<p>PHP7连接MongoDB语法如下：</p>
<pre><code class="language-php">//参数规则: mongodb://账号:密码@IP:端口/数据库
$manager = new \MongoDB\Driver\Manager("mongodb://php:123456@localhost:27017/php");
</code></pre>
<h3 id="插入数据">插入数据</h3>
<pre><code class="language-php">//1.连接MongoDB
$manager = new \MongoDB\Driver\Manager("mongodb://php:123456@localhost:27017/php");
//2.创建一个BulkWrite对象
$bulk = new \MongoDB\Driver\BulkWrite();
$bulk->insert(['name' => 'bashlog', 'age' => 26, 'email' => 'bashlog@foxmail.com']);
$bulk->insert(['name' => 'itbsl', 'age' => 12, 'email' => 'itbsl@foxmail.com']);
//3.执行插入
$manager->executeBulkWrite('php.stu', $bulk);
</code></pre>
<p>查看插入情况</p>
