Open Swoole 4.6.0 released: new HTTP API, Native CURL, Sockets hooks and more

Published: 10 January 2021

Swoole v4.6.0 is released with multiple new features and enhancement recently.

From Swoole v4.6.0, PHP 7.1 is no longer supported along with PHP version lifecycle.

Native CURL and Socket API hooks

With Swoole PHP, you can write the async applications with sequential codes in a Open Swoole fiber / coroutine to avoid callback hell like the other callback-based async frameworks.

CURL is widely used by all PHP applications. To transparently support PHP CURL API, previously the native CURL is replaced automatically in Swoole Server with the Swoole CURL written with PHP. Although most APIs are identical with the native CURL, you may run into a difference in some corner cases.

This has been improved in Swoole v4.6.0, you will use the async ready native CURL library hooked in the underlayer by Swoole Server.

New HTTP Request and Response API

It will be more flexible when using the new API to create or parse, modify the HTTP request object.

use Swoole\Http\Request;

$data = "GET /something?hello=world HTTP/1.1\r\n";
$data .= "Host:\r\n";
$data .= "Connection: keep-alive\r\n";
$data .= "User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36\r\n";
$data .= "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9\r\n";
$data .= "Accept-Encoding: gzip, deflate, br\r\n";

$request = Request::create(['parse_cookie' => false]);



$server = new swoole_http_server('', 9000, SWOOLE_BASE);
$server->on('request', function ($req, $resp) {
