I'm trying to text openswoole http server using docker image docker.io/openswoole/swoole:php7.4-alpine , but, I can't even find the function swoole_version(), I already check the php --ri openswoole, the libs is there. This is the output
openswoole
openswoole

I tried to search google/search engine, and git repo, seems they only pointed to not loaded lib or .so file, but in my case it's there. The 2nd try is to check the registered function seems only some of openswoole function is there.
I tried check using this code
<?php
$function = get_defined_functions()["internal"];
$result = array_filter($function, function($d) { return strpos($d, "swoole") !== false; });
var_dump($result);
The output is
array(23) {

}
Based on PHP.net docs (https://www.php.net/manual/en/ref.swoole-funcs.php), there should be a function called swoole_version, but seems the official docker image and the openswoole.so doesn't have it.
Is it by design? Or I need to pay something to use it? Or there are some conf that I need to enable?
Any pointer is really appreciated. Thanks
swoole and openswoole are not the same. The php docs are reffering to the swoole plugin and openswoole is a fork with a different documentation: https://openswoole.com/docs
You can use the following constants in openswoole: https://github.com/openswoole/ide-helper/blob/master/src/OpenSwoole/Constant.php#L11
\OpenSwoole\Constant::VERSION
Or you can use this function:
\OpenSwoole\Util::getVersion()
