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 collection.
// Create a Command Instance $createCollection = new MongoDBDriverCommand(["drop" => "sampleCollection"]); // Execute the command on the database $cursor = $manager->executeCommand("myDb", $createCollection);
Example
Try the following example to drop a collection 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 $dropCollection = new MongoDBDriverCommand(["drop" => "sampleCollection"]); // Execute the command on the database $cursor = $manager->executeCommand("myDb", $dropCollection); echo "Collection dropped." } catch (MongoDBDriverExceptionException $e) { echo "Exception:", $e->getMessage(), "n"; } ?>
