# Example Data

Some examples in this documentation use example data fixtures from
[zips.json][zips]. This is a dataset comprised of United States postal codes,
populations, and geographic locations.

Importing the dataset into MongoDB can be done in several ways. The following
example uses [mongodb extension][ext-mongodb]:

[zips]: http://media.mongodb.org/zips.json
[ext-mongodb]: http://php.net/mongodb

```
<?php

$file = 'http://media.mongodb.org/zips.json';
$zips = file($file, FILE_IGNORE_NEW_LINES);

$bulk = new MongoDB\Driver\BulkWrite;

foreach ($zips as $string) {
    $document = json_decode($string);
    $bulk->insert($document);
}

$manager = new MongoDB\Driver\Manager('mongodb://localhost');

$result = $manager->executeBulkWrite('demo.zips', $bulk);
printf("Inserted %d documents\n", $result->getInsertedCount());
```

Executing this script should yield the following output:

```
Inserted 29353 documents
```

You may also import the dataset using the [mongoimport][mongoimport] command,
which is included with MongoDB:

[mongoimport]: http://docs.mongodb.org/manual/reference/program/mongoimport/

```bash
$ mongoimport --db demo --collection zips --file zips.json --drop
```
