PHP & MongoDB - Delete Document
执行任何操作的第一步是创建一个管理器实例。
// Connect to MongoDB using Manager Instance
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");第二步是准备并执行一个 bulkWrite 对象，以删除集合中的记录。
// Create a BulkWrite Object
$bulk = new MongoDB\Driver\BulkWrite(['ordered' => true]);
$bulk->delete(['First_Name' => "Mahesh"]);
// Execute the commands.
$result = $manager->executeBulkWrite('myDb.sampleCollection', $bulk);Example
尝试以下示例，以删除 MongoDB 服务器中的集合中的文档 −
将以下示例复制粘贴到 mongodb_example.php −
<?php
try {
$bulk = new MongoDB\Driver\BulkWrite(['ordered' => true]);
$bulk->delete(['First_Name' => "Mahesh"]);
// connect to mongodb
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$result = $manager->executeBulkWrite('myDb.sampleCollection', $bulk);
echo "Document deleted."
} catch (MongoDB\Driver\Exception\Exception $e) {
echo "Exception:", $e->getMessage(), "\n";
}
?>
