Bug #74080 [NEW]: Provide an RFC7231 date time format

From: neclimdul at gmail dot com Operating system: PHP version: 7.1.1 Package: *General Issues Bug Type: Bug Bug description:Provide an RFC7231 date time format Description: ------------ There are a number of useful constants for formatting dates in PHP which cover most of the formats used on the internet. Unfortunately there is one missing format which can be pretty important, the one defined by RFC2616. All HTTP headers should follow this format. Because its a subset of RFC1123 that format is commonly substituted in PHP. This generally will work with permissive systems, however because the format provided by RFC1123 is system dependent it can provide strings that with more strict proxies will fail to parse. Generally that is UTC instead of the required GMT timezone. And old php.net documentation comment mentions this as well http://php.net/gmdate#25031. Because of this Drupal has a custom constant to be used in headers https://www.drupal.org/node/1918820 However because of PHP's audience I think it would be a handy feature for everyone to have the additional format constant. RFC2616 is actually obsoleeted by RFC7231 in 2014 so I would use this name as Drupal did but the format is the same. https://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.3 http://tools.ietf.org/html/rfc7231#section-7.1.1.1 -- Edit bug report at https://bugs.php.net/bug.php?id=74080&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74080&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74080&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74080&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74080&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74080&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74080&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74080&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74080&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74080&r=support Expected behavior: https://bugs.php.net/fix.php?id=74080&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74080&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74080&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74080&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74080&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74080&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74080&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74080&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74080&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74080&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74080&r=mysqlcfg
