The Splunk Software Development Kit for PHP
===========================================

[](#the-splunk-software-development-kit-for-php)

#### Version 1.0

[](#version-10)

The Splunk Software Development Kit (SDK) for PHP makes it easy for PHP applications to communicate with and control a Splunk server. Using the APIs exposed by the SDK, applications can start searches, display results, and perform administrative tasks.

### About Splunk

[](#about-splunk)

Splunk is a search engine and analytic environment that uses a distributed map-reduce architecture to efficiently index, search and process large time-varying data sets.

The Splunk product is popular with system administrators for aggregation and monitoring of IT machine data, security, compliance, and a wide variety of other scenarios that share a requirement to efficiently index, search, analyze, and generate real-time notifications from large volumes of time series data.

License
-------

[](#license)

The Splunk Software Development Kit for PHP is licensed under the Apache License 2.0. Details can be found in the file [LICENSE](https://github.com/splunk/splunk-sdk-php/blob/master/LICENSE).

Requirements
------------

[](#requirements)

The SDK requires PHP 5.2.11 or later with the SimpleXML extension. PHP 5.3.7 or later is highly recommended.

OpenSSL support for PHP is required to access Splunk over `https://` URLs.

If you're using PHP 5.3.6 or earlier, the cURL extension is required as well. Under this configuration, the SDK will not support streaming large results when accessing Splunk over `https://` URLs.

Getting Started
---------------

[](#getting-started)

If you haven't already installed Splunk, download it here: .

For more about installing and running Splunk plus system requirements, see [Installing & Running Splunk](http://dev.splunk.com/view/SP-CAAADRV).

Get a copy of the Splunk SDK for PHP from [GitHub](https://github.com/) by cloning the repository with git:

```
git clone https://github.com/splunk/splunk-sdk-php.git

```

Layout of the SDK
-----------------

[](#layout-of-the-sdk)

[](#examples)

To run the examples, you will need to install a web server locally that supports PHP.

- On Mac OS X, [MAMP](http://www.mamp.info/en/index.html) is recommended.
- On Windows, [XAMPP](http://www.apachefriends.org/en/xampp.html) is recommended. You will additionally need to configure PHP to support OpenSSL:
    - Open `C:\xampp\php\php.ini`.
    - Find the line `;extension=php_openssl.dll` and remove the leading semicolon (`;`).
    - Use the XAMPP Control Panel to restart Apache, if it was already running.
- On Linux, install Apache and PHP from your package manager.

Then, move the entire `splunk-sdk-php` directory (containing `examples` and `Splunk.php`) inside your web server's document root.

- For MAMP, the document root is located at: `/Applications/MAMP/htdocs/`
- For XAMPP, the document root is located at: `C:\xampp\htdocs\`

Finally, duplicate `settings.default.php` in the `examples` directory, rename the duplicate to `settings.local.php`, and then edit the file. Uncomment the `'port'`, `'username'`, and `'password'` fields and update the file with your Splunk server's credentials.

You should then be able to access the SDK examples via a URL similar to:

```
http://localhost:8888/splunk-sdk-php/examples/index.php

```

(You may need to alter the port of the URL to another value such as `8080` or `80`, depending on your web server.)

If you see an error similar to:

```
Login Failed.
Reason: fopen(https://localhost:8089/services/auth/login): failed to open stream: Invalid argument

```

this means that you need to enable support for OpenSSL in your PHP configuration (`php.ini`).

### Unit Tests

[](#unit-tests)

Requirements:

- [PHPUnit](http://www.phpunit.de/) 3.6 or later
- [Xdebug](http://xdebug.org/) 2.0.5 or later (for code coverage)
- Duplicate `settings.default.php` in the `tests` directory, rename the duplicate to `settings.local.php`, and then edit the file. Uncomment the `'port'`, `'username'`, and `'password'` fields and update the file with the credentials of a Splunk server reserved for testing.

To execute all unit tests, run:

```
phpunit tests

```

To execute only fast unit tests, run:

```
phpunit --exclude-group slow tests

```

To generate a code coverage report, run:

```
phpunit --coverage-html coverage tests
open coverage/Splunk.html

```

### API Documentation

[](#api-documentation)

Requirements:

- [phpDocumentor 2](http://www.phpdoc.org/)
- [GraphViz](http://www.graphviz.org/) (optional)
    - the **dot** command-line tool is used to render the class hierarchy diagram in the documentation

To generate the API documentation, run:

```
phpdoc -d Splunk -t apidocs

```

### Changelog

[](#changelog)

You can look at the changelog for each version [here](https://github.com/splunk/splunk-sdk-php/blob/master/CHANGELOG.md).

Quickstart
----------

[](#quickstart)

The PHP SDK provides an object-oriented interface for interacting with a Splunk server.

To use the SDK, first import `Splunk.php`. This will give you access to all `Splunk_*` classes.

```
require_once 'Splunk.php';

```

Then use an instance of `Splunk_Service` to connect to a Splunk server.

```
$service = new Splunk_Service(array(
    'host' => 'localhost',
    'port' => '8089',
    'username' => 'admin',
    'password' => 'changeme',
));
$service->login();

```

Once connected, you can manipulate various entities on the server, such as saved searches and search jobs.

For example, the following code runs a quick search and prints out the results.

```
// NOTE: The expression must begin with 'search ' or '| '
$searchExpression = 'search index=_internal | head 100 | top sourcetype';

// Create oneshot search and get results
$resultsXmlString = $service->getJobs()->createOneshot($searchExpression);
$results = new Splunk_ResultsReader($resultsXmlString);

// Process results
foreach ($results as $result)
{
    if ($result instanceof Splunk_ResultsFieldOrder)
    {
        // Process the field order
        print "FIELDS: " . implode(',', $result->getFieldNames()) . "\r\n";
    }
    else if ($result instanceof Splunk_ResultsMessage)
    {
        // Process a message
        print "[{$result->getType()}] {$result->getText()}\r\n";
    }
    else if (is_array($result))
    {
        // Process a row
        print "{\r\n";
        foreach ($result as $key => $valueOrValues)
        {
            if (is_array($valueOrValues))
            {
                $values = $valueOrValues;
                $valuesString = implode(',', $values);
                print "  {$key} => [{$valuesString}]\r\n";
            }
            else
            {
                $value = $valueOrValues;
                print "  {$key} => {$value}\r\n";
            }
        }
        print "}\r\n";
    }
    else
    {
        // Ignore unknown result type
    }
}

```

Core Concepts
-------------

[](#core-concepts)

### Entities and Collections

[](#entities-and-collections)

An *entity* is an object on a Splunk server. This includes saved searches, search jobs, indexes, inputs, and many others.

Each type of entity lives inside a *collection*. Each collection type can be accessed on the `Splunk_Service` object.

So, for example, to retrieve a list of saved searches or search jobs:

```
$savedSearches = $service->getSavedSearches()->items();  // in the default namespace
$jobs = $service->getJobs()->items();                    // in the default namespace

```

You can also retrieve a particular entity in a collection by name:

```
$topSourcetypesSearch = $service->getSavedSearches()->get('Top five sourcetypes');

```

### Namespaces

[](#namespaces)

An entity has a *namespace*, which corresponds to the entity's access permissions.

All functions that retrieve an individual entity or a list of entities can be provided a namespace argument. (If you omit this argument, the `Splunk_Service`'s default namespace will be used.)

So, for example, to retrieve the list of saved searches owned by user `admin`in the `search` app:

```
$savedSearches = $service->getSavedSearches()->items(array(
	'namespace' => Splunk_Namespace::createUser('admin', 'search'),
));

```

Or, to retrieve an individual entity in a namespace:

```
$topSourcetypesSearch = $service->getSavedSearches()->get(
	'Top five sourcetypes',
	Splunk_Namespace::createApp('search'));

```

If you typically access many objects in the same namespace, it is possible to pass a default namespace to the `Splunk_Service` constructor. This allows you to avoid passing an explicit namespace on every call to `get()` or `items()`.

```
$service = new Splunk_Service(array(
    ...
    'namespace' => Splunk_Namespace::createUser('admin', 'search'),
));
$service->login();

$jobs = $service->getJobs()->items();			// in the admin/search namespace
$indexes = $service->getIndexes()->items(array(	// in the system namespace
	'namespace' => Splunk_Namespace::createSystem(),
));

```

The types of namespaces are described here:

TypeNameDescriptionDefault`Splunk_Namespace::createDefault()`Contains entities owned by the authenticated user in that user's default app. For example, if you logged in to `Splunk_Service` as the user `admin` and the default application for that user was `search`, the default namespace would include all entities belonging to `admin` in app `search`. This namespace is used if no explicit namespace is provided.User`Splunk_Namespace::createUser($owner, $app)`Contains entities owned by a particular user in a particular app.App`Splunk_Namespace::createApp($app)`Contains entities in a particular app that have no owner.Global`Splunk_Namespace::createGlobal($app)`Contains entities in a particular app that have no owner and that are accessible to all apps.System`Splunk_Namespace::createSyste ()`Contains entities in the `system` app.Common Tasks
------------

[](#common-tasks)

### Running a Search with a Search Expression

[](#running-a-search-with-a-search-expression)

#### Oneshot Searches

[](#oneshot-searches)

For searches that run quickly with a small number of results, it is easiest to create a *oneshot* search:

```
// NOTE: The expression must begin with 'search ' or '| '
$searchExpression = 'search index=_internal | head 100 | top sourcetype';

// Create oneshot search and get results
$resultsXmlString = $service->getJobs()->createOneshot($searchExpression);
$results = new Splunk_ResultsReader($resultsXmlString);

// Process results
foreach ($results as $result)
{
    if ($result instanceof Splunk_ResultsFieldOrder)
    {
        // Process the field order
        // ...
    }
    else if ($result instanceof Splunk_ResultsMessage)
    {
        // Process a message
        print "[{$result->getType()}] {$result->getText()}\r\n";
    }
	else if (is_array($result))
    {
        // Process a row
        foreach ($result as $key => $valueOrValues)
        {
            // ...
        }
    }
    else
    {
        // Ignore unknown result type
    }
}

```

A oneshot search blocks until it completes and returns all results immediately.

#### Blocking Search Jobs

[](#blocking-search-jobs)

For searches that return a large number of results whose progress you don't need to monitor, it is easiest to create a *blocking* search job:

```
// NOTE: The expression must begin with 'search ' or '| '
$searchExpression = 'search index=_internal | head 1000';

// Create blocking search job and get results
$job = $service->getJobs()->create($searchExpression, array(
	'exec_mode' => 'blocking',
));
$results = $job->getResults();

// Process results
...

```

Blocking search jobs wait until all results are available.

#### Asynchronous (Normal) Search Jobs

[](#asynchronous-normal-search-jobs)

For most searches that could potentially return a large number of results, you should create an *asynchronous* (normal) search job.

Asynchronous jobs allow you to monitor their progress while they are running.

```
// NOTE: The expression must begin with 'search ' or '| '
$searchExpression = 'search index=_internal | head 10000';

// Create normal search job
$job = $service->getJobs()->create($searchExpression);

// Wait for job to complete and get results
while (!$job->isDone())
{
	printf("Progress: %03.1f%%\r\n", $job->getProgress() * 100);
	usleep(0.5 * 1000000);
	$job->refresh();
}
$results = $job->getResults();

// Process results
...

```

### Running a Saved Search

[](#running-a-saved-search)

You can create a normal search job based on a saved search by calling the `dispatch()` method on the `Splunk_SavedSearch` object.

```
$savedSearch = $service->getSavedSearches()->get('Top five sourcetypes');

// Create normal search job based on the saved search
$job = $savedSearch->dispatch();

// Wait for job to complete and get results
...

// Process results
...

```

### Running a Realtime Search

[](#running-a-realtime-search)

A realtime search must be run as an *asynchronous* search job. The *blocking* and *oneshot* modes do not work, because a realtime search never actually completes.

To get results from a realtime search, the `getResultsPreviewPage()` method must be used instead of the `getResults()` method.
