note 93004 added to function.stripos

The mail validator example is NON CONFORMANT with SMTP mail RFCs. Valid characters for Internet e-mail address are more than the ones listed here. Implementing such lame validator is a big disservice to the whole Internet. Those interested can read RFC 5322. In short, the valid characters are different on both sides of the @ sign, so, before applying this fast technique the address should be exploded into the two side strings, and then, use different valid character strings for the local-part and the domain. A local part can be any alphabetic or digit US-ASCII character plus "!#$%&'*+-/=?^_`{|}~", and then, if it is enclosed in double-quotes ("), it can be any US-ASCII character except double-quote (") and back-slash(\). The domain can be any printable US-ASCII characters not including "[", "]", or "\". And then, this could be overridden with the advent of internationalized domains, that can use UTF-8 character sets. Implementation of the validator is left as an exercise for the reader. ---- Server IP: 80.64.47.13 Probable Submitter: 80.38.252.251 ---- Manual Page -- http://www.php.net/manual/en/function.stripos.php Edit -- https://master.php.net/note/edit/93004 Del: integrated -- https://master.php.net/note/delete/93004/integrated Del: useless -- https://master.php.net/note/delete/93004/useless Del: bad code -- https://master.php.net/note/delete/93004/bad+code Del: spam -- https://master.php.net/note/delete/93004/spam Del: non-english -- https://master.php.net/note/delete/93004/non-english Del: in docs -- https://master.php.net/note/delete/93004/in+docs Del: other reasons-- https://master.php.net/note/delete/93004 Reject -- https://master.php.net/note/reject/93004 Search -- https://master.php.net/manage/user-notes.php
