crul is a R library for sending HTTP requests and web scraping. It is designed to be simple and easy to use, while still providing powerful functionality for working with HTTP requests and scraping web pages.

One of the main features of crul is its intuitive and easy-to-use syntax for sending HTTP requests. It allows you to easily specify the HTTP method, headers, and body of a request, and also provides a simple way to handle the response.

crul also has the ability to handle different types of requests and responses, including GET, POST, PUT, DELETE, and PATCH. It also support for handling redirects, cookies, and authentication.

Another feature of crul is its support for web scraping. The library provides a simple and efficient way to extract data from web pages, using a syntax similar to that of the XML and httr libraries. It also allows to easily filter the extracted data based on a specific criteria.

crul also supports parallel scraping, which allows to make multiple requests at the same time, thus speeding up the scraping process.

In addition to these features, crul has a good compatibility with other R packages such as tidyverse and purrr which facilitates the manipulation of the data obtained after scraping.

Buzz is a lightweight PHP library for issuing HTTP requests. It is built on top of the PHP curl extension and is designed to be easy to use and flexible.

While buzz isn't as feature rich as other clients it still supports http2 and is relatively easy to use.

Example Use

```r library(crul) # Sending a GET request to a website response <- HttpClient$new("https://www.example.com")$get() # Sending a POST request to a website request_body <- list(param1 = "value1", param2 = "value2") response <- HttpClient$new("https://www.example.com")$post(body = request_body) # Extracting the status code and body of the response status_code <- response$status_code() body <- response$body() # crul also allows easy asynchronous requests: urls <- c("https://www.example1.com", "https://www.example2.com", "https://www.example3.com") # Creating a list of request objects from urls requests <- lapply(urls, function(url) { HttpClient$new(url)$get() }) # Sending the requests asynchronously responses <- async(requests) # Extracting the status code and body of the responses status_codes <- lapply(responses, function(response) response$status_code()) bodies <- lapply(responses, function(response) response$body()) ```

```php use Buzz\Client\Curl; use Buzz\Message\Request; use Buzz\Message\Response; $client = new Curl(); // GET request $request = new Request('GET', 'http://httpbin.org/get'); $response = new Response(); $client->send($request, $response); echo $response->getContent(); //POST request $request = new Request('POST', '/api/resource', 'http://example.com'); $request->setContent(json_encode(['name' => 'John Doe'])); // we can also add headers or cookies: $request->addHeader('Content-Type: application/json'); $request->addHeader('Cookie: name=foobar'); $response = new Response(); $client->send($request, $response); echo $response->getContent(); // Buzz also supports http2 (see the 2.0 parameter) $response = $client->sendRequest( new Request('GET', 'https://http2.golang.org/serverpush', [], null, '2.0') ); ```
