Usage

Using Open API and PSR7

The library provides PSR7 http message support. Check \GSoares\GoogleTrends\Search\Psr7\Search.

Example:

<?php
use GSoares\GoogleTrends\Search\Psr7\Search;
use GSoares\GoogleTrends\Search\RelatedQueriesSearch;
use GuzzleHttp\Psr7\ServerRequest;

$search = new RelatedQueriesSearch();
// $search = new RelatedTopicsSearch();
// $search = new InterestOverTimeSearch();
// $search = new InterestByRegionSearch();

echo (string)(new Search($search))->search(ServerRequest::fromGlobals())->getBody();

You can check all Open API specs here.

And you can view the open api using swagger editor with (File -> Import URL -> Select openapi.yaml URL).

If you prefer your own implementation, please use the steps bellow:

1) Create a SearchFilter with your restrictions

$searchFilter = (new GSoares\GoogleTrends\Search\SearchFilter())
        ->withCategory(0) //All categories
        ->withSearchTerm('google')
        ->withLocation('US')
        ->withinInterval(
            new DateTimeImmutable('now -7 days'),
            new DateTimeImmutable('now')
        )
        ->withLanguage('en-US')
        ->considerWebSearch()
        # ->considerImageSearch() // Consider only image search
        # ->considerNewsSearch() // Consider only news search
        # ->considerYoutubeSearch() // Consider only youtube search
        # ->considerGoogleShoppingSearch() // Consider only Google Shopping search
        ->withTopMetrics()
        ->withRisingMetrics();
