From: marcus at synchromedia dot co dot uk Operating system: PHP version: 5.3.1 PHP Bug Type: Feature/Change Request Bug description: Add plain-text sanitizing to filter
Description: ------------ While the FILTER_FLAG_STRIP_LOW and FILTER_FLAG_STRIP_HIGH flags used with FILTER_SANITIZE_STRING work fine, They are just a bit blunt to be useful in practice. A more normal application would be to remove any 'funny' characters from plain text, so for example to allow chars 9, 10, 13, 32-126. This could be called FILTER_FLAG_PLAIN_TEXT. While this could be done using regex, it's probably the most common use case, so deserves a dedicated filter flag. This could be flipped around and be called FILTER_FLAG_ALLOW_WHITESPACE, overriding STRIP_LOW to allow chars 9, 10, 13 through. Similarly, a very common need is to normalize line breaks to \n, \r\n or \r. -- Edit bug report at http://bugs.php.net/?id=50309&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50309&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50309&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50309&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50309&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50309&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50309&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50309&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50309&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50309&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50309&r=support Expected behavior: http://bugs.php.net/fix.php?id=50309&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50309&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50309&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50309&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50309&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50309&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50309&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50309&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50309&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50309&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50309&r=mysqlcfg
