安装

打开网址： https://pecl.php.net/package/mongodb
选择适合自己的版本
打开php.ini 添加

extension=php_mongodb.dll

windows环境下查看是否安装成功

php -m|findstr mongodb
mongodb

php7需要使用全新的api，只支持MongoDB。只能写原生的SQL，使用起来非常不方便。
Mongo官网使用php封闭的一个扩展可以兼容原先的Mongo扩展，使用开发效率有很大的提升。

写个测试例子

$bulk = new MongoDB\Driver\BulkWrite();
$bulk->insert(['_id' => 1, 'x' => 1]);
$bulk->insert(['_id' => 2, 'x' => 2]);

$bulk->update(['x' => 2], ['$set' => ['x' => 1]], ['multi' => false, 'upsert' => false]);
$bulk->update(['x' => 3], ['$set' => ['x' => 3]], ['multi' => false, 'upsert' => true]);
$bulk->update(['_id' => 3], ['$set' => ['x' => 3]], ['multi' => false, 'upsert' => true]);

$bulk->insert(['_id' => 4, 'x' => 2]);

$bulk->delete(['x' => 1], ['limit' => 1]);



$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 100);
$result = $manager->executeBulkWrite('db.test', $bulk, $writeConcern);

printf("Inserted %d document(s)\n", $result->getInsertedCount());
printf("Matched  %d document(s)\n", $result->getMatchedCount());
printf("Updated  %d document(s)\n", $result->getModifiedCount());
printf("Upserted %d document(s)\n", $result->getUpsertedCount());
printf("Deleted  %d document(s)\n", $result->getDeletedCount());

foreach ($result->getUpsertedIds() as $index => $id) {
    printf('upsertedId[%d]: ', $index);
    var_dump($id);
}

/* If the WriteConcern could not be fulfilled */
if ($writeConcernError = $result->getWriteConcernError()) {
    printf("%s (%d): %s\n", $writeConcernError->getMessage(), $writeConcernError->getCode(), var_export($writeConcernError->getInfo(), true));
}
