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 bulkWrite object to delete record(s) in the collection.

// Create a BulkWrite Object
$bulk = new MongoDBDriverBulkWrite([''ordered'' => true]);

$bulk->delete([''First_Name'' => "Mahesh"]);

// Execute the commands.
$result = $manager->executeBulkWrite(''myDb.sampleCollection'', $bulk);

Example

Try the following example to delete a document of a collection in MongoDB server −

Copy and paste the following example as mongodb_example.php −

<?php
   try {
      $bulk = new MongoDBDriverBulkWrite([''ordered'' => true]);

      $bulk->delete([''First_Name'' => "Mahesh"]);

      // connect to mongodb
      $manager = new MongoDBDriverManager("mongodb://localhost:27017");

      $result = $manager->executeBulkWrite(''myDb.sampleCollection'', $bulk);

      echo "Document deleted."
   } catch (MongoDBDriverExceptionException $e) {	   
      echo "Exception:", $e->getMessage(), "n";
   }
?>

Output

Access the mongodb_example.php deployed on apache web server and verify the output.
