Yes, it is possible to customize the user-agent string in Goutte. Goutte is a web scraping library for PHP that provides an API to crawl websites and extract data from their HTML. It is built on top of Symfony components and uses Guzzle for HTTP requests.
To customize the user-agent string in Goutte, you can set the User-Agent header on the request. Here's an example of how to do it:
require 'vendor/autoload.php';
use Goutte\Client;
$client = new Client();
$crawler = $client->request('GET', 'https://example.com');
// Customize the user-agent string
$userAgent = 'Mozilla/5.0 (compatible; CustomBot/1.0; +http://www.example.com/bot)';
$client->setHeader('User-Agent', $userAgent);
// Now perform the request with the custom user-agent
$crawler = $client->request('GET', 'https://example.com');
// Do something with the crawler object...
In the above example, we first create a Goutte client and make a regular request. Then, we set a custom User-Agent string by calling $client->setHeader(). After that, we make another request, which will be sent with our custom user-agent string. This can be useful if you want to identify your crawler to websites or if you want to emulate a specific browser.
Keep in mind that it's important to respect the robots.txt of websites and their terms of service when using Goutte or any web scraping tools. Misrepresenting your bot as a human user with a deceptive user-agent can be considered unethical and, in some cases, may lead to legal consequences or being blocked by the website.
