Usage

Simple usage

Create an object and call the function getResults to get first 10 results

$googleSearch = new GoogleSearchApi(); // initialize

$results = $googleSearch->getResults('some phrase'); // get first 10 results for query 'some phrase' 

Do not forget to map namespace with, so sample controller will look like this (in min. way)

It is only example controller name, you can use whatever you want, this is notice mainly for novices in Laravel

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use jainsubh\GoogleSearchApi\GoogleSearchApi;

class GoogleSearchController extends Controller {
    
    public function index() {
        $googleSearch = new GoogleSearchApi(); // initialize

        $results = $googleSearch->getResults('some phrase'); // get first 10 results for query 'some phrase'// 
    }
}

You can also get information about the search like total records and search time

$googleSearch = new GoogleSearchApi(); // initialize

$results = $googleSearch->getResults('some phrase'); // get first 10 results for query 'some phrase' 
$info = $googleSearch->getSearchInformation(); // get search information

Advanced usage

You can use any parameter supported at Google. List of parameters is here: https://developers.google.com/custom-search/json-api/v1/reference/cse/list#parameters

E.g. you want to get next 10 results

$parameters = array(
    'start' => 10, // start from the 10th results,
    'num' => 10 // number of results to get, 10 is maximum and also default value
);

$search_type = 'site_restrict'// if empty by default Google Custom Search JSON API would work

$googleSearch = new GoogleSearchApi(); // initialize

$results = $googleSearch->getResults('some phrase', $parameters, $search_type); // get second 10 results for query 'some phrase'

You can also get the raw result from Google including other information Full list of response variables is available here: https://developers.google.com/custom-search/json-api/v1/reference/cse/list#response

$googleSearch = new GoogleSearchApi(); // initialize

$results = $googleSearch->getResults('some phrase'); // get first 10 results for query 'some phrase'
$rawResults = $googleSearch->getRawResults(); // get complete response from Google

For getting the number of results only use

$googleSearch = new GoogleSearchApi(); // initialize

$results =  $googleSearch->getResults('some phrase'); // get first 10 results for query 'some phrase'
$noOfResults = $googleSearch->getTotalNumberOfResults(); // get total number of results (it can be less than 10)

If you have more engines / more api keys, you can override the config variables with following functions

$googleSearch = new GoogleSearchApi(); // initialize

$googleSearch->setEngineId('someEngineId'); // sets the engine ID
$googleSearch->setApiKey('someApiId'); // sets the API key

$results =  $googleSearch->getResults('some phrase'); // get first 10 results for query 'some phrase'
