Bug #55560 [Opn->Csd]: filter_var($e, FILTER_VALIDATE_EMAIL) won't validate spaces in quoted strings

Edit report at https://bugs.php.net/bug.php?id=55560&edit=1 ID: 55560 User updated by: fredgandt at hotmail dot com Reported by: fredgandt at hotmail dot com Summary: filter_var($e, FILTER_VALIDATE_EMAIL) won't validate spaces in quoted strings -Status: Open +Status: Closed Type: Bug Package: Mail related Operating System: Windows XP (SP3) PHP Version: 5.3SVN-2011-09-01 (SVN) Block user comment: N Private report: N New Comment: Really sorry. RFC is hard to read so I relied on Wikipedia (usually very good with this kind of thing). Spaces aren't ever allowed. Not even within quotes. Going to edit Wikipedia now instead of waste your time. Forgive? ;-) Previous Comments: ------------------------------------------------------------------------ [2011-09-01 11:38:43] fredgandt at hotmail dot com Description: ------------ --- From manual page: http://www.php.net/filter.filters.validate --- IMPORTANT: I am a learner. Sorry if I am wasting your time. Also GoDaddy don't supply much in the way of detail about what version is running. All I know is that it is 5.3.? I have asked for the rest but am still waiting. Using filter_var($e, FILTER_VALIDATE_EMAIL) where $e is a submitted email address that according to RFC 5321 and Wikipedias clearer to understand interpretation of it should be considered valid, the return can be invalid where spaces are featured within quoted strings. e.g. A-Za-z0-9."?Oooh![what]{fun}|is|!".gladthisisn'tmyaddress@[32.64.128.1] == valid (impressive) "Fred Gandt"@fredgandt.com == invalid Take the space out and "FredGandt"@fredgandt.com == valid I've tested all the most unusual combinations I can think of and FILTER_VALIDATE_EMAIL seems to only fail with spaces being disallowed outright rather than only being disallowed when not enclosed by quotes (as with other otherwise disallowed chars). If my interpretation of RFC 5321 is wrong and spaces are in fact never allowed (even when enclosed by quotes) please forgive my impertinence. Love PHP. Very slick and user friendlyness abounds! Test script: --------------- <html><body><br> <form action="" method="post"> <input type="text" name="email" size="100"> <input type="submit" value="POST"><br><br> <?php $e=$_REQUEST["email"]; $result=filter_var($e, FILTER_VALIDATE_EMAIL); if($result){echo($e."<br><br><b style=\"color:#008800;\">Valid Email Address</b>");} else{echo($e."<br><br><b style=\"color:#ff0000;\">Invalid Email Address</b>");} ?> </form></body></html> Expected result: ---------------- Test script provides form entry field "input type="text"" Fill in "textbox" with email address having a local-part with a quoted string containing spaces. e.g. "Fred Gandt"@fredgandt.com Submit EXPECT: Return (echo) == Valid Actual result: -------------- OBSERVE: Return (echo) == Invalid ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55560&edit=1
