Swoole PHP v4.6.3 have just been released with multiple new features and enhancement today including set Content-Length header, compression_min_length and more…

Namespace alias functions are added for go and defer

Two new functions with namespace are added: Swoole\Coroutine\go and Swoole\Coroutine\go.

These functions can be used when you have disabled the short named functions godefer.

Example of Swoole\Coroutine\go and Swoole\Coroutine\go:

<?php

use function Swoole\Coroutine\go;
use function Swoole\Coroutine\run;
use function Swoole\Coroutine\defer;

run(function () {
    defer(function () {
        echo "co1\n";
    });
    go(function () {
        usleep(100000);
        echo "co2\n";
    });
});

compression_min_length

To specify the minimum length of the response to compress, use the compression_min_length directive. The default is 20 bytes.

<?php

$http->set(['compression_min_length' => 128]);

Content-Length header support

From Swoole PHP 4.6.3, you can set the Content-Length header if the content length is known or you like to change the default Content-Length header calculated by Swoole Server.

Example:

<?php
use Swoole\Http\Server;
use Swoole\Http\Request;
use Swoole\Http\Response;

$http = new Server('0.0.0.0', 9000);

$http->on('Request', function (Request $request, Response $response) {
    $msg = 'Hello, Swoole';
    $response->header('Content-Length', 5);
    //$response->header('Content-Length', strlen($msg));
    $response->end($msg);
});

$http->start();
