A simple one-time use function to generate the inside part of a PHP class based on functions from a text file. Pulls and uses the function's prototype/synopsis from the PHP manual, as well as adds the full prototype/synopsis and description in a comment. This makes it easy to convert procedural style PHP extensions into classes. Written specific…

   *
   * This code will turn a function list into the inside part of a class, with
   * the synopsis, and each member calling the original procedural style function.
   * It was written to turn ncurses_* functions into a class.
   *
   * TO USE, load a text file into a file (ncurses.txt in this revision), with
   * a one function name per line (no () or other characters, just the function
   * name, like 'foo' not 'foo()' or otherwise). IF you copied directly from
   * manual, and it has a &mdash; followed by the description, there is code in
   * there that will remove the &mdash.
   *
   * Now download  the PHP manual, the HTML "many files" version and untar -xzvf
   * the file into the same directory as this script.  The function synopsis and
   * description will be pulled from there.
   *
   * It is assumed that for each member you want to chop off everything before
   * the first underscore.  so ncurses_getyx() becomes $yourOO->getyx(). 
   * If this isn't the case, modify lines dealing with $inner_function
   *
   * KNOWN BUGS:
   * - Doesn't unescape HTML entities from the manual.  It's a one line fix.
   * - Dosn't handle optional parameters.  In the code generated you will have,
   *   e.g. fuction foo($bar, [$spaz]) if $spaz was optional in the synopsis.
   *   ncurses only had one function like this, so I left it out.  Additionally,
   *   it might be useful to ensure you don't miss those (they will need manual
   *   handling)
