# Link Preview
A PHP class that consumes an HTTP(S) link and returns an array of preview information. Think of Facebook sharing -
whenever you paste a link, it goes to specified page and fetches some details.

Initially based on [kasp3r/link-preview](https://github.com/kasp3r/link-preview) that seems to be abandoned.

This fork is special in that it doesn't come with any specific HTTP implementation but instead lets you inject a PSR-17 Factory and a PSR-18 Client. Giving you the freedom to use whatever you like.

## Dependencies

* PHP >= 7.0
* Symfony DomCrawler >= 3.0

## Installation via Composer

To install simply run:

```
composer require dusterio/link-preview
```

Or add it to `composer.json` manually:

```json
{
    "require": {
        "marcelklehr/link-preview": "~1.2"
    }
}
```

## Direct usage

```php
use Marcelklehr\LinkPreview\Client;

$previewClient = new Client(/*your http implementation here*/);

// Get previews from all available parsers
$previews = $previewClient->getLink('https://www.boogiecall.com/en/Melbourne')->getPreviews();

// Only get preview data from specific parser
$preview = $previewClient->getPreview('general');

// Convert output to array
$preview = $preview->toArray();
```

**Output**

```
array(4) {
  ["basic"]=>array(2){
    ["title"]=>
    string(44) "Events, parties & live concerts in Melbourne"
    ["description"]=>
    string(107) "List of events in Melbourne. Nightlife, best parties and concerts in Melbourne, event listings and reviews."
  }
  ["image"]=>array(2){
    ["large"]=>
    string(94) "https://cdn.boogiecall.com/media/images/872398e3d9598c494a2bed72268bf018_1440575488_7314_s.jpg"
    ["small"]=>
    string(94) "https://cdn.boogiecall.com/media/images/872398e3d9598c494a2bed72268bf018_1440575488_7314_s.jpg"
  }
}
```

### YouTube example

```php
use Marcelklehr\LinkPreview\Client;

$previewClient = new Client(/*your http implementation here*/);

// Only parse YouTube specific information
$preview = $previewClient->getLink('https://www.youtube.com/watch?v=v1uKhwN6FtA')->getPreview('youtube');

var_dump($preview->toArray());
```

**Output**

```
array(2) {
  ["video"]=>array(2) {
    ["embed"]=>
    string(128) "<iframe id="ytplayer" type="text/html" width="640" height="390" src="http://www.youtube.com/embed/v1uKhwN6FtA" frameborder="0"/>"
    ["id"]=>
    string(11) "v1uKhwN6FtA"
  }
}
```
