Difficult project of correlating inserted in-line styles in RTE and then removing all styles and scripts

This basically defines the BoxToDb() which is in common.php and is called whenever we come out of a RTE box to add data to the db. 

attempt to sanatize as per these instructions
    • unfortunately that would also remove most of the rte formatting  ... but i fixed that
  • use php strip tags function as per this comment
    • this is working
  • remove all styles except those known to be generated by rte
    • use preg_replace

      • The e modifier makes preg_replace() treat the replacement parameter as PHP code after the appropriate references substitution is done. Tip: make sure that replacement constitutes a valid PHP code string, otherwise PHP will complain about a parse error at the line containing preg_replace().
        What they don't tell you is that you should enclose the replacement string in quotes if you are using the /e modifier
      • Remove the styles of my known classess too.  They will be applied by the style sheet on display based upon the class.  However:
        • must reapply them on edit 
      • rte box styles to preserve this is working
      • however still need to parse into the style literal because rte box applies multiple styles in the same statement  .... done
        • font-style: italic;
        • font-weight: bold;
        • text-align: right;
        • text-align: justify;
        • text-align: left;
        • "margin-left: NNNpx;" (whenre NNN any number<rediculous)
        • "color: rgb(102, 0, 204);" (where the rgb vary)
  • Replaced single quotes as follows to  get some bizarre strings through  sql
    • $text=str_replace("'","&apos;",$text);
    • Hopefully this will not get us into problems later.
Time for another shakedown
