PHP 8.3 nightly missing Unicode PCRE properties

curry684 commented 10 months ago

The following code does not work in PHP 8.3 nightly:

var_dump(preg_match('#\\p{cyrillic}#u', 'Пример')); # Should be 1
var_dump(preg_match('#\\p{cyrillic}#u', 'Latin'));  # Should be 0

Even though it should: https://3v4l.org/4sRgY#v8.2.11

You can see it fail in https://github.com/omines/antispam-bundle/actions/runs/6769796730/job/18396922196:

1) /home/runner/work/antispam-bundle/antispam-bundle/src/Validator/Constraints/BannedScriptsValidator.php:34
preg_match(): Compilation failed: unknown property name after \P or \p at offset 13

8.1 and 8.2 are passing the same test suite. My local 8.3 install passes it as well.

As far as I can see this error results from the PCRE extension being built without --enable-unicode-properties flag. It's pretty much impossible to validate that hypothesis though as the switch is not exposed through PHP.

I've set up a dedicated test case, turns out the code successfully runs on 7.3 to 8.2 only.

PHP 5.6 to 7.2 and the nightlies of 8.3 and 8.4 fail.
