Req #81469 [Opn]: preg_replace(): add support for named capture groups

Edit report at https://bugs.php.net/bug.php?id=81469&edit=1 ID: 81469 Updated by: nikic@php.net Reported by: wim at squeezely dot tech Summary: preg_replace(): add support for named capture groups Status: Open Type: Feature/Change Request Package: PCRE related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: TBH I don't think this is worthwhile anymore at this point. With preg_replace_callback you can do: preg_replace_callback('/(?<namedGroup>[a-z]+)$/', fn($m) => "ice-cream-with-$m[namedGroup]", 'I-like-chocolate-sprinkles')); Which is not much worse than dedicated syntax, and gives you the full generality of PHP without any questions about edge-case behavior.
