PHP & MongoDB – Drop Database



First step to do any operation is to create a Manager instance.

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

Second step is to prepare and execute a command to drop the database.

// Create a Command Instance
$dropDatabase = new MongoDBDriverCommand(["dropDatabase" => 1]);

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

Example

Try the following example to delete a database in MongoDB server −

Copy and paste the following example as mongodb_example.php −

<?php
   try {
      // connect to mongodb
      $manager = new MongoDBDriverManager("mongodb://localhost:27017");

      // Create a Command Instance
      $dropDatabase = new MongoDBDriverCommand(["dropDatabase" => 1]);

      // Execute the command on the database
      $cursor = $manager->executeCommand("myDb", $dropDatabase);
   
      echo "Database dropped."
   } catch (MongoDBDriverExceptionException $e) {	   
      echo "Exception:", $e->getMessage(), "n";
   }
?>
