Our production php use the old one,Do you mean the latest version php fix the bug? I found source code as below in my php: void php_filter_validate_email(PHP_INPUT_FILTER_PARAM_DECL) /* {{{ */ { /* * The regex below is based on a regex by Michael Rushton. * However, it is not identical. I changed it to only consider routeable * addresses as valid. Michael's regex considers a@b a valid address * which conflicts with section 2.3.5 of RFC 5321 which states that: * * Only resolvable, fully-qualified domain names (FQDNs) are permitted * when domain names are used in SMTP. In other words, names that can * be resolved to MX RRs or address (i.e., A or AAAA) RRs (as discussed * in Section 5) are permitted, as are CNAME RRs whose targets can be * resolved, in turn, to MX or address RRs. Local nicknames or * unqualified names MUST NOT be used. * * This regex does not handle comments and folding whitespace. While * this is technically valid in an email address, these parts aren't * actually part of the address itself. * * Michael's regex carries this copyright: * * Copyright © Michael Rushton 2009-10 * http://squiloople.com/ * Feel free to use and redistribute this code. But please keep this copyright notice. * */ const char regexp[] = "/^(?!(?:(?:\\x22?\\x5C[\\x00-\\x7E]\\x22?)| (?:\\x22?[^\\x5C\\x22]\\x22?)){255,})(?!(?:(?:\\x22?\\x5C[\\x00-\\x7E]\\x22?)| (?:\\x22?[^\\x5C\\x22]\\x22?)){65,}@)(?:(?:[\\x21\\x23- \\x27\\x2A\\x2B\\x2D\\x2F-\\x39\\x3D\\x3F\\x5E-\\x7E]+)|(?:\\x22(?:[\\x01- \\x08\\x0B\\x0C\\x0E-\\x1F\\x21\\x23-\\x5B\\x5D-\\x7F]|(?:\\x5C[\\x00- \\x7F]))*\\x22))(?:\\.(?:(?:[\\x21\\x23-\\x27\\x2A\\x2B\\x2D\\x2F- \\x39\\x3D\\x3F\\x5E-\\x7E]+)|(?:\\x22(?:[\\x01-\\x08\\x0B\\x0C\\x0E- \\x1F\\x21\\x23-\\x5B\\x5D-\\x7F]|(?:\\x5C[\\x00-\\x7F]))*\\x22)))*@(?:(?:(?!.* [^.]{64,})(?:(?:(?:xn--)?[a-z0-9]+(?:-[a-z0-9]+)*\\.){1,126}){1,}(?:(?:[a-z][a- z0-9]*)|(?:(?:xn--)[a-z0-9]+))(?:-[a-z0-9]+)*)|(?:\\[(?:(?:IPv6:(?:(?:[a-f0-9] {1,4}(?::[a-f0-9]{1,4}){7})|(?:(?!(?:.*[a-f0-9][:\\]]){7,})(?:[a-f0-9]{1,4}(?:: [a-f0-9]{1,4}){0,5})?::(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?)))|(?:(?:IPv6: (?:(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){5}:)|(?:(?!(?:.*[a-f0-9]:){5,})(?:[a-f0-9] {1,4}(?::[a-f0-9]{1,4}){0,3})?::(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3}:)?)))?
