Installation

Composer

composer require antheta/falcon

Usage

Running the scraper:

$falcon = Falcon::getInstance()->run("https://example.com/");
$result = $falcon->parse()->results(); // use all available parsers and get all results

The example above scrapes the url and returns an array.

Use specific parsers

If you wish to get specific resources from the results

$falcon = Falcon::getInstance()->run("https://example.com/");
// only returns emails
$emails = $falcon->parse(["email", "ip"])->emails(); 

Methods

Helper methods for returning the results:

Name
results
emails
phonenumbers
ipaddresses
forms
links
images
stylesheets
scripts
fonts

Custom regexes

To add your own regexes to parsers you can just use the addRegexes helper:

// this will attempt to parse emails with the given regex
$falcon = Falcon::getInstance()
          ->addRegexes("email", ["/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-ddd]+/i"])
          ->run("https://example.com/")->parse()->emails();

// you can extend this to other parsers as well and add as many regexes as needed
$falcon = Falcon::getInstance()
            // regexes for emails
            ->addRegexes("email", [
              "/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-ddd]+/i",
              "/[\._a-zA-Z0-9-]+\(at\)[\._a-zA-Z0-9-]+/i",
            ])
            // regexes for phonenumbers
            ->addRegexes("phonenumber", [
              "/([\+]?[(]?[0-9]{3}[)]?[-\s\.]?[0-9]{3}[-\s\.]?[0-9]{4,12})/",
            ])
            ->run("https://example.com/")
            ->parse()
            ->results();

Custom parsers

With custom parsers you are in control of what kind of data will the parser return:

$falcon = Falcon::getInstance();

$falcon->addParser("myCustomParser", fn ($payload) => MyParser($payload));

function MyParser($payload) {
  // your custom logic here
}

// or
$falcon->addParser("myCustomParser", function($payload) {
  // your custom logic here
});

// result from your parser
$falcon->parse("myCustomParser")->results()["myCustomParser"];

Custom drivers

Drivers are used for scraping the sites and returning the html to falcon. Drivers can also be used to write completely custom logic and saving it to falcon for later use. Start by creating your own driver class that extends the DriverInterface interface and implement the driver specific logic within class.

$falcon = Falcon::getInstance();

$falcon->addDrivers([
  "myDriver" => MyDriver::class
]);

Scraping dynamic content

You could migrate from hQuery to headless JavaScript browser like CapserJS & Phantom to load dynamic content. This way you can also scrape data that is loaded dynamically (after the inital page load).
