Php Mongodb 简明教程
PHP & MongoDB - Drop Collection
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命令,以删除集合。
// Create a Command Instance
$createCollection = new MongoDB\Driver\Command(["drop" => "sampleCollection"]);
// Execute the command on the database
$cursor = $manager->executeCommand("myDb", $createCollection);
Example
尝试以下示例,以删除 MongoDB 服务器中的集合 −
将以下示例复制粘贴到 mongodb_example.php −
<?php
try {
// connect to mongodb
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
// Create a Command Instance
$dropCollection = new MongoDB\Driver\Command(["drop" => "sampleCollection"]);
// Execute the command on the database
$cursor = $manager->executeCommand("myDb", $dropCollection);
echo "Collection dropped."
} catch (MongoDB\Driver\Exception\Exception $e) {
echo "Exception:", $e->getMessage(), "\n";
}
?>
