symfony/http-client v5.4.35

The symfony/http-client is a versatile and potent PHP package that aids in the fetching of HTTP resources. This can either be carried out synchronously or asynchronously, depending on the unique requirements of your project. Its distinctive capabilities make it an appealing choice for PHP developers that require dependable HTTP client solutions. The symfony/http-client package strengthens the programming process with its robust framework.

The symfony/http-client package is fairly straightforward to use in your PHP projects. Firstly, you would need to install it via Composer - the PHP package management system, using the following command:

composer require symfony/http-client

Following this, to fetch a URL's content for instance, you would need to import and instantiate the HttpClient object and call the 'send' method. See the example below:

use Symfony\Component\HttpClient\HttpClient;

$client = HttpClient::create();
$response = $client->request('GET', 'https://www.example.com');

$statusCode = $response->getStatusCode();
$content = $response->getContent();

Another powerful feature of the symfony/http-client package is its support for asynchronous requests. This means that you can send many requests, and process their responses later when they are returned. Here's an example:

use Symfony\Component\HttpClient\HttpClient;

$client = HttpClient::create();
$responses = [];
for ($i = 0; $i < 10; $i++) {
    $responses[] = $client->request('GET', 'https://www.example.com?page='.$i);
}

foreach ($responses as $response) {
    // processing the responses only when they arrive
    echo $response->getContent();
}

This package also makes it convenient to handle exceptions, retries and timeouts.
