The aspell() functions allows you to check the
     spelling on a word and offer suggestions.
    
Note: 
     This extension has been removed from PHP and is no
     longer available as of PHP 4.3.0. If you want to use spell-checking
     capabilities in PHP, use pspell instead.
     It uses pspell library and works with newer versions of aspell.
    
     aspell works only with very old (up to .27.* or so) versions of
     aspell library. Neither this module, nor those versions of aspell
     library are supported any longer. You need the aspell library, available
     from: http://aspell.sourceforge.net/.
    
  In PHP 4, these functions are only available if PHP was
  configured with --with-aspell=[DIR].
