Bug #69140 [Opn]: FILTER_VALIDATE_EMAIL not RFC 822 compliant

Edit report at https://bugs.php.net/bug.php?id=69140&edit=1 ID: 69140 Updated by: aharvey@php.net Reported by: info at linux-web-development dot de Summary: FILTER_VALIDATE_EMAIL not RFC 822 compliant Status: Open Type: Bug Package: Filter related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: The code does actually document that comments aren't handled, but that never made it to the docs. I'll fix that. I don't think this is worth fixing (the validation code is terrifying enough as it is, and, seriously, comments in e-mail addresses?), but I'll leave this open in case someone can provide a clean PR.

So far I could find the following compliant addresses not validating: foo@example foo@(bar)example.com foo@example.com(bar) Generally PHP should at comply with RFC 822 when validating mail addresses, otherwise the filter function is useless. Test script: --------------- var_dump(filter_var('foo@example', FILTER_VALIDATE_EMAIL)); Expected result: ---------------- string(11) "foo@example" Actual result: -------------- bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69140&edit=1
