SerpScraper

The purpose of this library is to provide an easy, undetectable, and captcha resistant way to extract search results from popular search engines like Google and Bing.

Installation

The recommended way to install this is via Composer:

composer require athlon1600/serpscraper "^4.0"

Extracting Search Results From Google

<?php

use SerpScraper\Engine\GoogleSearch;

$page = 1;

$google = new GoogleSearch();

// all available preferences for Google
//$google->setPreference('google_domain', 'google.lt');
//$google->setPreference('date_range', 'hour');

$results = array();

do {

    $response = $google->search("how to scrape google", $page);

    // error field must be empty otherwise query failed
    if(empty($response->error)){

        $results = array_merge($results, $response->results);
        $page++;

    } else if($response->error == 'captcha'){

        // read below
        break;
    }

} while ($response->has_next_page);

Solve Google Search captchas automatically

For this to work, you will need to register for 2captcha.com services, and get an API key. It is also highly recommended to use a proxy server.
Install a private proxy server on your own VPS here:

<?php

use SerpScraper\Engine\GoogleSearch;
use SerpScraper\GoogleCaptchaSolver;

$google = new GoogleSearch();

$browser = $google->getBrowser();
$browser->setProxy('PROXY:IP');

$solver = new GoogleCaptchaSolver($browser);

while(true){
    $response = $google->search('famous people born in ' . mt_rand(1500, 2020));

    if ($response->error == 'captcha') {

        echo "Captcha detected!" . PHP_EOL;

        $temp = $solver->solveUsingTwoCaptcha($response, '2CAPTCHA_API_KEY', 90);

        if ($temp->status == 200) {
            echo "Captcha solved successfully!" . PHP_EOL;
        } else {
            echo 'Solving captcha has failed...' . PHP_EOL;
        }

    } else {
        echo "OK. ";
    }

    sleep(2);
}

Extract Search Results from Bing

<?php

use SerpScraper\Engine\BingSearch;

$bing = new BingSearch();
$results = array();

for($page = 1; $page < 10; $page++){

    $response = $bing->search("search bing using php", $page);
    if($response->error == false){
        $results = array_merge($results, $response->results);
    }

    if($response->has_next_page == false){
        break;
    }
}

var_dump($results);
