Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and

[7] Fix | Delete

trivial to integrate with web services.

[8] Fix | Delete

[9] Fix | Delete

- Simple interface for building query strings, POST requests, streaming large

[10] Fix | Delete

uploads, streaming large downloads, using HTTP cookies, uploading JSON data,

[11] Fix | Delete

etc...

[12] Fix | Delete

- Can send both synchronous and asynchronous requests using the same interface.

[13] Fix | Delete

- Uses PSR-7 interfaces for requests, responses, and streams. This allows you

[14] Fix | Delete

to utilize other PSR-7 compatible libraries with Guzzle.

[15] Fix | Delete

- Abstracts away the underlying HTTP transport, allowing you to write

[16] Fix | Delete

environment and transport agnostic code; i.e., no hard dependency on cURL,

[17] Fix | Delete

PHP streams, sockets, or non-blocking event loops.

[18] Fix | Delete

- Middleware system allows you to augment and compose client behavior.

# Send an asynchronous request.

});
