Doc #65890 [NEW]: PCRE escape sequence \R undocumented

From: krewecherl at gmail dot com Operating system: PHP version: Irrelevant Package: Documentation problem Bug Type: Documentation Problem Bug description:PCRE escape sequence \R undocumented Description: ------------ This manual page on PCRE escape sequences http://www.php.net/manual/en/regexp.reference.escape.php is missing the \R (BSR, backslash-R) escape. One of the user comments mentions it, but not quite correctly. Whether \R matches only CR, NL, and CR+LF, or *any* Unicode line break sequence, depends on how the pcre extension is configured (flag: --enable-bsr-anycrlf), see the README in ext/pcre/pcrelib. The default mode is BSR_UNICODE, in which \R matches \r, \n, \r\n, U+0085, U+2028, and U+2029. I can confirm this for the default Ubuntu packages, but I don't have any information about other distributions/packages. In any case, the escape sequence should be documented. -- Edit bug report at https://bugs.php.net/bug.php?id=65890&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65890&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=65890&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65890&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65890&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65890&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65890&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65890&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65890&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=65890&r=support Expected behavior: https://bugs.php.net/fix.php?id=65890&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65890&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65890&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65890&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65890&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65890&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65890&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=65890&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65890&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65890&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65890&r=mysqlcfg
