PHP & MongoDB - Drop Database
First step to do any operation is to create a Manager instance.
// Connect to MongoDB using Manager Instance $manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
Second step is to prepare and execute a command to drop the database.
// Create a Command Instance $dropDatabase = new MongoDB\Driver\Command(["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 MongoDB\Driver\Manager("mongodb://localhost:27017"); // Create a Command Instance $dropDatabase = new MongoDB\Driver\Command(["dropDatabase" => 1]); // Execute the command on the database $cursor = $manager->executeCommand("myDb", $dropDatabase); echo "Database dropped." } catch (MongoDB\Driver\Exception\Exception $e) { echo "Exception:", $e->getMessage(), "\n"; } ?>
