Differences between version 3 and 2 of »AvoidMagicQuotes«

  [MarioSalzer "milky"]:
  The 'magic_quotes' in my opinion is the most stupid thing the Zend people
  added to PHP. Because it is a config setting, it is set differently on many
  servers, thus making it hard to get a PHP script run equal on many systems.
  The magic_quotes add backslashes to GET, POST and COOKIE variables to give
  novices a chance to write 'safe' PHP database usage code without having to
  learn programming...(!)

  Yes, I'd really like to say the magic_quotes are for stupids.
  Even if the magic_quotes are now off by default in recent PHP versions,
  they still are a problem, because many providers still have poorly written
  code (not managing to use addslashes() or similar before writing to database)
  and thus enforce people also to live with the antiquatic_quotes (there is
  the .htaccess workaround, ok, but it is not safe or always possible to use
  it).
  This problem for example lead to constructs like "eventually_add_slashes()"
  functions in many projects (PhpNuke has such one for example). This slows
  down everything and makes code unreadable - in ewiki such an
  eventually_add_slashes() function had to be deployed around 100 times to
  work around the antique_quotes 'feature'. So my approach was the
  "fragments/strip_wonderful_slashes.php" include, which redecodes any
  garbaged $_REQUEST variable.
  %%%
  This is a good thing, because ewiki's database code cares about adding
  backslashes before sending commands to the database - and in fact PHP's
  magic_quotes sense of adding quotes wasn't even capable of doing it
  correctly, because different databases (ADODB) use different escape chars!
  For an bad example of problems with magic_quotes just see the
  sourceforge.net site - their software is also not aware enough of their own
  PHP interpreter having the trouble_quotes enabled, so you\\\\\'ll often see
  backslashes appear before quotes, often you\\\\\\\\\\'ll see a long line of
  \\\\\\\\\\\\\\\\\\\\\ backslashes, where you wouldn\\\\\\\\\\\'t expect
  (they also have problems with \newlines, but that\\\'s another story ;)
