PHP 和 MongoDB - 連線資料庫

執行任何操作的第一步是建立一個 Manager 例項。

// Connect to MongoDB using Manager Instance
$manager = new MongoDB\Driver\Manager("mongodb://:27017");

第二步是在資料庫上準備並執行一個命令，如果資料庫不存在，則 MongoDB 會自動建立它。

// Create a Command Instance
$statistics = new MongoDB\Driver\Command(["dbstats" => 1]);

// Execute the command on the database
$cursor = $manager->executeCommand("myDb", $statistics);

示例

嘗試以下示例連線到 MongoDB 伺服器 -

複製並貼上以下示例作為 mongodb_example.php -

<?php
   try {
      // connect to mongodb
      $manager = new MongoDB\Driver\Manager("mongodb://:27017");

      echo "Connection to database successfully";
      $statistics = new MongoDB\Driver\Command(["dbstats" => 1]);
      $cursor = $manager->executeCommand("myDb", $statistics);
      $statistics = current($cursor->toArray());
      echo "<pre>"; 
      print_r($statistics); 
      echo "</pre>";
   } catch (MongoDB\Driver\Exception\Exception $e) {	   
      echo "Exception:", $e->getMessage(), "\n";
   }
?>

輸出

訪問部署在 Apache Web 伺服器上的 mongodb_example.php 並驗證輸出。
