Edit report at http://bugs.php.net/bug.php?id=53722&edit=1 ID: 53722 Comment by: deadalnix at gmail dot com Reported by: romain dot riviere at gmail dot com Summary: FILTER_VALIDATE_EMAIL fails on numeric TLDs Status: Bogus Type: Bug Package: Filter related Operating System: Linux PHP Version: 5.3.5 Block user comment: N Private report: N New Comment: Hi, I want to enlight the PHP team about https://www.42registry.org/ . This TLD is more and more recognized and used, and we will reach a point where not supporting numerical TLD will be a major problem. Previous Comments: ------------------------------------------------------------------------ [2011-03-21 03:02:54] barkerjr at barkerjr dot net This bug should be reopened. We don't want PHP to be broken in the event that a numeric TLD is created. ------------------------------------------------------------------------ [2011-02-18 16:24:09] romain dot riviere at gmail dot com Precisely. FILTER_VALIDATE_EMAIL should validate *technically* correct email addresses, not just ICANN-correct ones. It is already the case for .foo or .bar TLDs, it just needs to do the same for numeric TLDs, because from a technical point of view, there are no different: old restrictions in old RFCs have all been superseded now. ------------------------------------------------------------------------ [2011-02-13 23:30:16] frank9321 at gmail dot com I think that Romain in right. There are numeric TLDs (like the .42 TLD wich is taking off), and sometimes, as Romain said, you use such TLDs in your LAN. So, really, the FILTER_VALIDATE_EMAIL should accept numeric TLDs. It isn't because the ICANN said that there couldn't be numeric TLDs that there aren't. ------------------------------------------------------------------------ [2011-01-18 14:15:16] romain dot riviere at gmail dot com There ARE numeric TLDs, even though they are not made public. I have one on my LAN. The filter should probably not rely on what is believed to exist, but on what is technically feasible. In other words, if I can get email on the address johndoe@domain.123 (and again, YES, it works), then FILTER_VALIDATE_EMAIL should not reject such an address. ------------------------------------------------------------------------ [2011-01-18 14:03:15] iliaa@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php There are no numeric TLDs, the e-mail filters supports IP based e-mail addresses however. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
