IMPORTANT: It seems ZipArchive::RDONLY was introduced since PHP 7.4.3

huh, good find, I didn't consider that the argument would not have also existed since ZipArchive was added in 5.2

Some things to consider

  1. PHP < 7.4 is out of support according to https://www.php.net/supported-versions.php
  2. Debian bullseye+ and Ubuntu 20.04+ package manager ships PHP 7.4+
  3. Debian buster and Ubuntu 18.04 package manager ships PHP 7.2
  4. Red Hat 8+ have PHP 7.4+ available in shipped packages (Red Hat 7 does not ship any PHP it looks like)
  5. Fedora project's EPEL registry has packages for 8.2
  6. Rocky Linux appstream includes 7.4+

Uhmm I'm not bold enough to raise PHP 7.4 as minimum version just for this exact line, since probably the workaround here is reasonable readable and minimal. Here an example ↑

Yeah that should be a separate discussion. I'll copy that comment into T15047.

✅ The strict check is correct since it must return true on success
