Edit report at https://bugs.php.net/bug.php?id=75207&edit=1 ID: 75207 Comment by: Philip dot Hazel at gmail dot com Reported by: qflbapp at gmail dot com Summary: preg_match bug Status: Open Type: Bug Package: PCRE related Operating System: Linux Ubuntu PHP Version: 7.1.9 Block user comment: N Private report: N New Comment: It has now been reported to the PCRE maintainers, but with no information about the PCRE version. I cannot reproduce a problem with the given pattern - it gives an immediate "unmatched parentheses" error, with or without the backslashes (does PHP remove them?).
