Because its CA was added to the internal bundle since then.

Why invalid? Should be "issuer unknown". Add https://ca.rootdir.org/ca.cer to your system PKI.

Tested with PHP 7.4, nothing changed.

<?php
print file_get_contents(__FILE__);
var_dump(PHP_VERSION);
var_dump(ini_get("openssl.cafile"));
var_dump(ini_get("openssl.capath"));
var_dump(substr(file_get_contents('https://ca.rootdir.org/'), 0, 16));
var_dump(error_get_last());

With Cygwin PKI:

<?php
print file_get_contents(__FILE__);
var_dump(PHP_VERSION);
var_dump(ini_get("openssl.cafile"));
var_dump(ini_get("openssl.capath"));
var_dump(substr(file_get_contents('https://ca.rootdir.org/'), 0, 16));
var_dump(error_get_last());
string(6) "7.4.16"
string(76) "C:\Programs\Cygwin_64\etc\pki\ca-trust\extracted\openssl\ca-bundle.trust.crt"
string(35) "C:\Programs\Cygwin_64\usr\ssl\certs"
string(16) "<html>
<body>
<h"
NULL

Without specific PKI:

<?php
print file_get_contents(__FILE__);
var_dump(PHP_VERSION);
var_dump(ini_get("openssl.cafile"));
var_dump(ini_get("openssl.capath"));
var_dump(substr(file_get_contents('https://ca.rootdir.org/'), 0, 16));
var_dump(error_get_last());
string(6) "7.4.16"
string(0) ""
string(0) ""
string(0) ""
array(4) {
  ["type"]=>
  int(2)
  ["message"]=>
  string(83) "file_get_contents(https://ca.rootdir.org/): failed to open stream: operation
failed"
  ["file"]=>
  string(71) "C:\Users\anrdaemon\Documents\Bugs\PHP\76694-openssl-system-PKI\test.php"

}

Well, requesting https://packagist.org works for me with and
without setting openssl.cacert, but requesting
https://ca.rootdir.org/ does not even work from a browser
(NET::ERR_CERT_AUTHORITY_INVALID).

So maybe this has been fixed in the meantime.  Or do you still
experience the issue with any of the actively supported PHP
versions[1].

Same test with Cygwin PKI

string(6) "7.1.22"
string(76) "C:\Programs\Cygwin_64\etc\pki\ca-trust\extracted\openssl\ca-bundle.trust.crt"
string(35) "C:\Programs\Cygwin_64\usr\ssl\certs"
<and no error messages>

Yes, browsers that use system CA store (IE, Chrome-based) operate correctly.

Yes, I can use OpenSSL functionality (particularly curl) without an issue after pointing openssl.ca*
settings to Cygwin PKI that contains the necessary root CA certificate.

The further error message wasn't helping.

And no, it doesn't work with packagist either.

<?php
print file_get_contents(__FILE__);
var_dump(PHP_VERSION);
var_dump(ini_get("openssl.cafile"));
var_dump(ini_get("openssl.capath"));
file_get_contents('https://packagist.org/');
?>
string(6) "7.1.22"
string(0) ""
string(0) ""
