Lightweight cURL client intergration of the PHP PSR-7 HTTP message interface.


Install via Composer.

$ composer require pdeans/http


The cURL client is built on top of Zend Framework's Diactoros strict PSR-7 implementation.

Configuring the Client

The client accepts an optional associative array of curl options as the first parameter to configure the cURL client. However, please note that the following cURL options cannot be set in order to comply with PSR-7 standards. Instead, these options should be provided as part of the request options:


The following is an example of how to create and configure the client with options.

use pdeans\Http\Client;

$client = new Client([

On a side note, the client may also accept optional 2nd and 3rd parameters of pdeans\Http\Contracts\MessageFactoryInterface and pdeans\Http\Contracts\StreamFactoryInterface implementations respectively. The client uses instances of pdeans\Http\Factories\MessageFactory and pdeans\Http\Factories\StreamFactory by default if these parameters are omitted.

HTTP Requests

The client comes bundled with helper methods to provide a convenient way for issuing the supported HTTP request methods.

GET, HEAD, and TRACE methods take the following parameters:

  • String representation of the target url OR an object implmentation of Psr\Http\Message\UriInterface
  • Associative array of headers (header_name => header_value)

POST, PUT, PATCH, OPTIONS, and DELETE methods take the two parameters listed above, plus the following 3rd parameter for the request body:

  • String of request body data OR an object implmentation of Psr\Http\Message\StreamInterface

Note that the pdeans\Http\Factories\StreamFactory and pdeans\Http\Factories\UriFactory classes provide create methods to implement the PSR interfaces listed above if the object integrations are needed for the request.

Example requests:

// GET request with header
$response = $client->get('http://example.com/1', ['custom-header' => 'header/value']);

// GET request without header
$response = $client->get('http://example.com/2');

// Response body output
echo (string)$response->getBody();

$headers = [
    'Content-Type'  => 'application/json',
    'Accept'        => 'application/json',
    'Authorization' => 'Basic '.base64_encode('username:password'),

$data = json_encode(['json' => 'json data']);

// POST request with headers and request body
$response = $client->post('http://example.com/4', $headers, $data);

// Response body output
echo (string)$response->getBody();

// Response headers output
echo '<pre>', print_r($response->getHeaders()), '</pre>';

// Response status code output
echo $response->getStatusCode();

// Response reason phrase output
echo $response->getReasonPhrase();

If more control over the request is needed, the helper methods can be bypassed altogether and the underlying main request method, sendRequest, can be called directly. This method accepts an object implementation of Psr\Http\Message\RequestInterface. The library provides a factory implementation for creating a request object, pdeans\Http\Factories\MessageFactory->createRequest()

HTTP Responses

Each HTTP request returns a Response object. The Response object is an instance of the Laminas\Diactoros\Response class, which implements the Psr\Http\Message\RequestInterface.

Further Reading

As this library is a layer built upon existing libraries and standards, I recommend that you read through some of their documentation to get a better understanding of how the various components work.
