Fixes issue #969.

This isn't compatible with PHP 5, which the 0.4 branch still supports.

Hey @mbabker

Just found my way to this issue after upgrading my Symfony 5.4 to 6.1 with gos/web-socket-bundle. I took a peek at the 0.5 branch, but it still has PHP 5 as supported in its composer.json too.

Is the plan for Ratchet 0.5 to drop PHP 5 and pick up PHP 8.1? Is there a way to progress this forward so that Ratchet can be used with Symfony 6.1?

Many thanks.

Damo.
