This is a small standalone PHP library that helps with parsing *and creating* `Link` header contents with `rel=""` attributes as it is used in the context of RESTful web services.

It is a tolerant parser, silently accepting invalid input. You can use the API functions to check if a given `rel` exists.

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

[](#installation)

The preferred way to install library is through [composer](http://getcomposer.org/download/).

Either run

```
composer require graviton/link-header-rel-parser

```

or add

```
"graviton/link-header-rel-parser": "*",
```

to the require section of your `composer.json`.

Examples
--------

[](#examples)

### Parsing headers

[](#parsing-headers)

Parsing an existing header is easy, just pass the plain header *contents* to the static function:

```
$header = '; rel="self", '; rel="next"';
$linkHeader = LinkHeader::fromString($header);

$selfUrl = $linkHeader->getRel('self')->getUri(); // will output 'http://localhost/service/self'
```

If you are using Symfony, just fetch the Link header from the `Request` or `Response` object and pass it to the library.

### Creating headers

[](#creating-headers)

You can create header contents programmatically:

```
$header = new LinkHeader();
$header->add(new LinkHeaderItem('http://localhost?limit(10,10)', 'self'));
$header->add(new LinkHeaderItem('http://localhost?limit(10,30)', 'next'));
$header->add(new LinkHeaderItem('http://localhost?limit(10,0)', 'prev'));

echo (string) $header;
```

Will produce

```
; rel="self", ; rel="next", ; rel="prev"

```

### Manipulating existing

[](#manipulating-existing)

Combining both methods above, you can also parse existing headers, manipulate them and render them.

```
$header = '; rel="self", '; rel="next"';
$linkHeader = LinkHeader::fromString($header);

$linkHeader->add(new LinkHeaderItem('http://localhost?limit(10,10)', 'prev'));
$linkHeader->removeRel('next');
$header->getRel('self')->setUri('http://newhost');

echo (string) $header;
```

Will produce

```
; rel="self", ; rel="prev"

```
