pcntl_waitid already has the parameter documented. Can you align the explanation: https://www.php.net/manual/en/function.pcntl-waitid.php?

The documentation for wexitstatus says:
This function is only useful if pcntl_wifexited() returned true.
So, is a wifexited call missing here? Looking more carefully at the example, it uses quite a few functions from the pcntl extension. It might make sense to include it in https://www.php.net/manual/en/pcntl.example.php instead.

Considering how often this is repeated, an XInclude or XML entity to have consistent wording would be better
