使用PHP驱动程序在Mongo中使用点符号

Question

This example shows a simple insert:

$collection = (new MongoDB\Client)->example->users;

$insertOneResult = $collection->insertOne([
    'username' => 'admin',
    'email' => '[e-mail]',
    'name' => 'Admin User',
]);

printf("Inserted %d document(s)
", $insertOneResult->getInsertedCount());

var_dump($insertOneResult->getInsertedId());

... but using the latest PHP driver, I get an error if I have a . in the collection name (collection.attribute), for example:

$collection = (new MongoDB\Client)->collection.attribute->users;

Answer 1

This works:

$collection = (new MongoDB\Client)->{'collection.attribute'}->users;
