   5   this strips all "\" from $_REQUEST and

   7
   8   just include() it before ewiki.php

  12   for Apache+mod_php you should however rather use the
  13   [.htaccess] PHP reconfiguration trick:
  14     php_flag magic_quotes_gpc off
  15     php_flag magic_quotes_runtime off

  23  #-- Moodle always addslashes to everything so
  24  #-- we strip them back again here to allow
  25  #-- the wiki module itself to add them before
  26  #-- insert. Strange triple add-strip-add but
  27  #-- this was the best way to solve problems
  28  #-- without changing how the rest of the
  29  #-- module works.
