get-from
========

[](#get-from)

Function to retrieve values from objects without painfully checking if the value `isset`. Inspired by and ported from the great [get-in](https://github.com/igorw/get-in) library for arrays from Igor Wiedler.

For example, to access a nested property `->foo->bar->baz`, you must do something like this:

```
$baz = (isset($data->foo->bar->baz)) ? $data->foo->bar->baz : null;
```

Enough already! get-from provides a better way:

```
$baz = florianec\get_from($data, ['foo', 'bar', 'baz']);
```

`get_from` is specially handy when dealing with deeply nested objects like those generated by [SimpleXML](http://at2.php.net/manual/en/book.simplexml.php).

Installation
------------

[](#installation)

Through composer:

```
$ composer require florianeckerstorfer/get-from:~1.0
```

Usage
-----

[](#usage)

### get\_in

[](#get_in)

Retrieve value from a nested structure using a list of keys:

```
$data = new \stdClass();
$data->foo = new \stdClass();
$data->foo->bar = new \stdClass();
$data->foo->bar->baz = 'oof';

$name = florianec\get_from($data, ['foo', 'bar', 'baz']);
//= 'oof'
```

Non existent keys return `null`:

```
$data = new \stdClass();
$data->foo = 'bar';

$baz = florianec\get_from($data, ['baz']);
//= null
```

You can provide a default value that will be used instead of `null`:

```
$data = new \stdClass();
$data->foo = 'bar';

$baz = florianec\get_from($data, ['baz'], 'qux');
//= 'qux'
```

### Version 1.0 (9 March 2014)

[](#version-10-9-march-2014)

- Initial release

Inspiration
-----------

[](#inspiration)

This library is a complete ripoff of Igor Wiedler's [get-in](https://github.com/igorw/get-in) library. Even this README file is largely inspired by Igors work. Scandalous.

I created this library/function when I wanted to clean up the code dealing with XML from an external web service and I realised that `get-in` only works for arrays and not for objects.
