Quandl Elephant API
===================

[](#quandl-elephant-api)

This project is a fork of [php-quandl](https://github.com/DannyBen/php-quandl), a great API to provide easy access to the [Quandl API](https://www.quandl.com/help/api) using PHP.

The name of this project was changed to answer the [PHP Licensing](http://php.net/license/).

Install
-------

[](#install)

To install with composer:

```
composer require royopa/quandl-elephant-api
```

Examples
--------

[](#examples)

This is a basic call. It will return a PHP object with price data for AAPL:

```
use Royopa\Quandl;

$api_key = "YOUR_KEY_HERE";
$quandl  = new Quandl($api_key);
$data    = $quandl->getSymbol("GOOG/NASDAQ_AAPL");
```

You may pass any parameter that is mentioned in the Quandl documentation:

```
use Royopa\Quandl;

$quandl = new Quandl($api_key);
$data = $quandl->getSymbol($symbol, [
	"sort_order"      => "desc",
	"exclude_headers" => true,
	"rows"            => 10,
	"column"          => 4,
]);
```

The date range options get a special treatment. You may use any date string that PHP's `strtotime()` understands.

```
use Royopa\Quandl;

$quandl = new Quandl($api_key, "csv");
$data = $quandl->getSymbol($symbol, [
	"trim_start" => "today-30 days",
	"trim_end"   => "today",
]);
```

You can also search the entire Quandl database and get a list of supported symbols in a data source:

```
use Royopa\Quandl;

$quandl = new Quandl($api_key);
$data   = $quandl->getSearch("crude oil");
$data   = $quandl->getList("WIKI", 1, 10);
```

More examples can be found in the [examples.php](https://github.com/DannyBen/php-quandl/blob/master/examples.php) file

Caching
-------

[](#caching)

You may provide the `quandl` object with a cache handler function. This function should be responsible for both reading from your cache and storing to it.

See the [example\_cache.php](https://github.com/DannyBen/php-quandl/blob/master/example_cache.php) file.

Reference
---------

[](#reference)

### Constructor and public properties

[](#constructor-and-public-properties)

The constructor accepts two optional parameters: `$api_key` and `$format`:

```
$quandl = new Quandl("YOUR KEY", "csv");
```

You may also set these properties later:

```
$quandl->api_key = "YOUR KEY";
$quandl->format  = "json";
```

`$format` can be one of `csv`, `xml`, `json`, and `object` (which will return a php object obtained with `json_decode()`).

After each call to Quandl, the property `$last_url` will be set for debugging and other purposes. In case there was an error getting the data from Quandl, the result will be `false` and the property `$error` will contain the error message.

### getSymbol

[](#getsymbol)

```
mixed getSymbol( string $symbol [, array $params ] )
```

Returns an object containing data for a given symbol. The format of the result depends on the value of `$quandl->format`.

The optional parameters array is an associative `key => value`array with any of the parameters supported by Quandl.

You do not need to pass `auth_token` in the array, it will be automatically appended.

### getSearch

[](#getsearch)

```
mixed getSearch( string $query [, int $page, int $per_page] )
```

Returns a search result object. Number of results per page is limited to 300 by default.

Note that currently Quandl does not support CSV response for this node so if `$quandl->format` is "csv", this call will return a JSON string instead.

### getList

[](#getlist)

```
mixed getList( string $source [, int $page, int $per_page] )
```

Returns a list of symbols in a given source. Number of results per page is limited to 300 by default.

Tests
-----

[](#tests)

From the project directory, tests can be ran using:

```
./vendor/bin/phpunit
```
