[1] <https://www.php.net/manual/en/filter.filters.sanitize.php> Previous Comments: ------------------------------------------------------------------------ [2020-07-07 07:20:01] cyberline@php.net Description: ------------ In all PHP Versions except 5.3.2 the following Script will return false for FILTER_VALIDATE_EMAIL while FILTER_SANITIZE_EMAIL does NOTHING to the input email. While the Provided email is a valid return path, i excpect that VALIDATE_EMAIL will return the string provided and not false. Test script: --------------- <?php $email = '3e9.1c.4UB2NC76N436-3SP03.test-EW3LBM-M6H4BG-0-1.mobil.123456.989=test.de@smtp20.test.com'; var_dump(\filter_var($email, FILTER_VALIDATE_EMAIL)); var_dump($email === \filter_var($email, FILTER_SANITIZE_EMAIL)); Expected result: ---------------- string(89) "3e9.1c.4UB2NC76N436-3SP03.test-EW3LBM-M6H4BG-0-1.mobil.123456.989=test.de@smtp20.test.com" bool(true) Actual result: -------------- bool(false) bool(true) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79802&edit=1
