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

From: Operating system: Windows XP (SP3) PHP version: 5.3SVN-2011-09-01 (SVN) Package: Mail related Bug Type: Bug Bug description:filter_var($e, FILTER_VALIDATE_EMAIL) won't validate spaces in quoted strings Description: ------------ --- From manual page: http://www.php.net/filter.filters.validate --- IMPORTANT: I am a learner. Sorry if I am wasting your time. Also GoDaddy don't supply much in the way of detail about what version is running. All I know is that it is 5.3.? I have asked for the rest but am still waiting. Using filter_var($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 bug report at https://bugs.php.net/bug.php?id=55560&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55560&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55560&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55560&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55560&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55560&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55560&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55560&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55560&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55560&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55560&r=support Expected behavior: https://bugs.php.net/fix.php?id=55560&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55560&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55560&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55560&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55560&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55560&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55560&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55560&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55560&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55560&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55560&r=mysqlcfg
