Summary: pcntl_async_signals not available in phpdbg
Status: Re-Opened
Type: Bug
Package: phpdbg
Operating System: CentOS 7
PHP Version: 7.2.10

New Comment:
Seems my quick assessment above was wrong. I've just build with
`./configure --disable-all --disable-cgi --enable-debug
--enable-pcntl` and ext/pcntl is available for phpdbg (without the
PR).

I am trying to connect a GitHub PR to this issue, but the bug-tracking is giving me error 500 :-(
So the PR is here:
https://github.com/php/php-src/pull/3534

This is true for Ubuntu.
On CentOS7/Webtatic instead they are not explicitly disabled, and that what leads to:
[Uncaught Error in /tmp/test.php on line 2]
Error: Call to undefined function pcntl_async_signals() in /tmp/test.php:2
Stack trace:
#0 {main}
So either webtatic "forgot" to enable pcntl_async_signals during phpdbg compilation, or
there's a general reason why this can not be available in phpdbg at all, which bring me to the
reason why opened the bug report in the first place: there's no documentation around stating
that phpdbg does not support pcntl_async_signals (at least I wasn't able to find it), however
both on CentOS and Ubuntu this is not an available feature (either not compiled in, or explicitly
disabled). Is this:
* a bug (for CentOS/Ubuntu)
* a missed documentation (for PHP.net as a whole and/or phpdbg)
* a missing feature (for PHP.net as whole and/or phpdbg)

ext/pcntl declares itself to be a cli only extension[1]. cli only
extensions can presently only be enabled for cli, cgi and
embed[2], which might have been an oversight.

The php.ini you see is actually provided by way of php7.2-common's php.ini-production. We
can't do anything for it.
https://packages.ubuntu.com/bionic/php7.2-phpdbghttps://packages.ubuntu.com/bionic/php7.2-common
You could make a bug report for -phpdbg to do something else. Or for -common to document why those
functions are disabled, which is almost definitely for security and/or technical reasons.
