Edit report at http://bugs.php.net/bug.php?id=54233&edit=1 ID: 54233 Comment by: carsten_sttgt at gmx dot de Reported by: flood at itnews-bg dot com Summary: PHP Filter email doesn't work properly Status: Open Type: Bug Package: *General Issues Operating System: Slackware 13x86_64 PHP Version: 5.3.5 Block user comment: N Private report: N New Comment: That's the correct behavior. FILTER_SANITIZE_EMAIL on: ?“?‰?“a‚¬?“?S?“a‚¬_?“a€??“a€¦?“??' this.is.a.testing@email.com results in: ???a??S?a_?a??a???'this.is.a.testing@email.com and that's a valid email address according to (at least) RFC822 (sorry, don't know which RFC PHP is exactly using for FILTER_VALIDATE_EMAIL. Should be documented) Previous Comments: ------------------------------------------------------------------------ [2011-03-11 22:44:21] flood at itnews-bg dot com Hey, It seems the filter function is not working some times. You can see in the test script that the email is returned as a valid though it's not quite. ------------------------------------------------------------------------ [2011-03-11 22:43:36] flood at itnews-bg dot com Description: ------------ Hey, It seems the filter function is not working some times.

Testing script: <?php $email = "?“?‰?“a‚¬?“?S?“a‚¬_?“a€??“a€¦?“??' this.is.a.testing@email.com"; var_dump(filter_var(filter_var($email,FILTER_SANITIZE_EMAIL), FILTER_VALIDATE_EMAIL)); ?> Test script: --------------- <?php $email = "?“?‰?“a‚¬?“?S?“a‚¬_?“a€??“a€¦?“??' this.is.a.testing@email.com"; var_dump(filter_var(filter_var($email,FILTER_SANITIZE_EMAIL), FILTER_VALIDATE_EMAIL)); ?> Expected result: ---------------- It should return a false boolean. This is not a valid email. Actual result: -------------- Returns an invalid email: ???a??S?a_?a??a???'this.is.a.testing@email.com ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54233&edit=1
