Bug #76919 [NEW]: REMOTE_ADDR in square brackets

From: a dot schilder at gmx dot de Operating system: Windows 10 PHP version: 7.3.0RC1 Package: Built-in web server Bug Type: Bug Bug description:REMOTE_ADDR in square brackets Description: ------------ One of my scripts failed because the built-in web server returned the IPv6 value in $_SERVER['REMOTE_ADDR'] with square brackets. The value was '[::1]' (PHP 7.3RC1) instead of '::1' (PHP 7.2.4), although it is no used as a host here (see RFC 3986, 3.2.2). BTW: Also filter_var('[::1]', FILTER_VALIDATE_IP) fails (as expected). Test script: --------------- echo $_SERVER['REMOTE_ADDR'] Expected result: ---------------- ::1 Actual result: -------------- [::1] -- Edit bug report at https://bugs.php.net/bug.php?id=76919&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=76919&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=76919&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=76919&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=76919&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=76919&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=76919&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=76919&r=needscript Try newer version: https://bugs.php.net/fix.php?id=76919&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=76919&r=support Expected behavior: https://bugs.php.net/fix.php?id=76919&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=76919&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=76919&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=76919&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=76919&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=76919&r=dst IIS Stability: https://bugs.php.net/fix.php?id=76919&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=76919&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=76919&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=76919&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=76919&r=mysqlcfg
