Swoole Demo outdated? about php-sse

[hhxsv5]

Maybe you forgot to enable swoole extension in php.ini, use php --ri swoole or php -m|grep swoole to confirm whether swoole is enabled.

[FelixMittermeier]

Yeah, it is enabled. Both

/opt/plesk/php/8.0/bin/php -m | grep swoole
swoole

and

php -m | grep swoole
swoole

are showing the correct output but unfortunately I am still not able to use the extension in my php scripts. When using https://github.com/hhxsv5/php-sse/blob/master/examples/sse-swoole.php for testing purposes I am still getting an error
Class "Swoole\Http\Server" not found.

Everything has been restarted multiple times so this shouldn't be an issue.

[hhxsv5]

Whether different versions of php are installed, try to run sse-swoole.php with the php absolute path.
/opt/plesk/php/8.0/bin/php sse-swoole.php
And show me the output about /opt/plesk/php/8.0/bin/php --ri swoole please.

Okay, so /opt/plesk/php/8.0/bin/php --ri swoole

outputs:

Directly running ssw-swoole.php leads to same error as described above.

Don't know if it is relevant in this context but I also asked the swoole maintainers at their GitHub page and they wrote it cannot be run in cli mode. But what's the point when execution by a user from a browser ist not possible? Your example looks like it is possible so I am a bit confused right now.

[hhxsv5]

Yes, the Swoole example can only be run in cli mode, not in FPM.

php sse-swoole.php

Swoole has a built-in Http server, which is started in cli mode, and you should directly access http://127.0.0.1:5200/ in browser. not http://127.0.0.1/sse-swoole.php.

[FelixMittermeier]

Yeah that finally makes sense and would maybe explain the described behavior. I am going to try it out today or the next days.
Thank you very much for your help ☺️

[hhxsv5]

Anytime.

[FelixMittermeier]

For another reason I cannot test it right now unfortunately. But as said before I really think the way you described works out.
Closing the issue now because the former question has been answered. ☺️
