Intro

What is simplon/spider?

Spider parses a given html document and aggregates all essential data:

• title
• description
• keywords
• all h1 contents
• open-graph tags
• twitter tags
• all images

It basically gives you sort of the same response as Facebook's scraper. However, Facebook's scraper does not give you all essential data.

Facebook scraper response:

{
   "og_object":{
      "id":"379786107965",
      "description":"Find the latest breaking news and information on the top stories, weather, business, entertainment, politics, and more. For in-depth coverage, CNN provides special reports, video, audio, photo galleries, and interactive guides",
      "title":"Breaking News, U.S., World, Weather, Entertainment & Video News - CNN.com",
      "type":"website",
      "updated_time":"2015-09-01T13:15:53+0000",
      "url":"http:\/\/www.cnn.com\/"
   },
   "share":{
      "comment_count":0,
      "share_count":1340555
   },
   "id":"http:\/\/cnn.com"
}

Spider response:

{
   "title":"Breaking News, U.S., World, Weather, Entertainment & Video News - CNN.com",
   "description":"Find the latest breaking news and information on the top stories, weather, business, entertainment, politics, and more. For in-depth coverage, CNN provides special reports, video, audio, photo galleries, and interactive guides",
   "keywords":"breaking news, news online, U.S. news, world news, developing story, news video, CNN news, weather, business, money, politics, law, technology, entertainment, education, travel, health, special reports, autos, CNN TV",
   "url": "http:\/\/www.cnn.com\/",
   "images":[

      "http://i2.cdn.turner.com/cnnnext/dam/assets/110902115913-gates-of-auschwitz-large-169.jpg"
   ],

Examples

The following examples are straight forward and should not require any additional explaintation.

Parse by fetching the page first

use Simplon\Spider\Spider;

// fetch and parse
$data = Spider::fetchParse('http://cnn.com');

echo json_encode($data); // json encode result

Parse by existing html

use Simplon\Spider\Spider;

// page html
$html = '...';

// fetch and parse
$data = Spider::parse($html, 'http://cnn.com'); // URL is needed to rebuild absolute image paths

echo json_encode($data); // json encode result

Result in both cases

{
   "title":"Breaking News, U.S., World, Weather, Entertainment & Video News - CNN.com",
   "description":"Find the latest breaking news and information on the top stories, weather, business, entertainment, politics, and more. For in-depth coverage, CNN provides special reports, video, audio, photo galleries, and interactive guides",
   "keywords":"breaking news, news online, U.S. news, world news, developing story, news video, CNN news, weather, business, money, politics, law, technology, entertainment, education, travel, health, special reports, autos, CNN TV",
   "url": "http:\/\/www.cnn.com\/",
