I know this post is a bit old  but thought I would add the functions I use that take into account any filters and any  lt   CDATA some stuff   gt  content you want to safely exclude  Simply add to your functions php file and use anywhere you would like  such as  content 53   or excerpt 27   Enjoy    limit excerpt function excerpt  limit       excerpt   explode      get the excerpt     limit     if  count  excerpt  gt   limit        array pop  excerpt        excerpt   implode  quot   quot   excerpt             else        excerpt   implode  quot   quot   excerpt           excerpt   preg replace                    excerpt     return  excerpt       limit content  function content  limit       content   explode      get the content     limit     if  count  content  gt   limit        array pop  content        content   implode  quot   quot   content             else        content   implode  quot   quot   content           content   preg replace                 content      content   apply filters  the content    content       content   str replace     gt        amp gt     content     return  content

This also balances HTML tags so that they won t be left open and doesn t break words   add filter  the content    break text    function break text  text        length   500      if strlen  text  lt  length 10  return  text   don t cut if too short       break pos   strpos  text        length    find next space after desired length      visible   substr  text  0   break pos       return balanceTags  visible

Or even easier and without the need to create a filter  use PHP s mb strimwidth to truncate a string to a certain width  length   Just make sure you use one of the get  syntaxes  For example with the content    lt  php  content   get the content    echo mb strimwidth  content  0  400           gt    This will cut the string at 400 characters and close it with      Just add a  read more -link to the end by pointing to the permalink with get permalink      lt a href   lt  php the permalink     gt   gt Read more  lt  a gt    Of course you could also build the read more in the first line  Than just replace       with   lt a href      get permalink        gt  Read more  lt  a gt

You could use a Wordpress filter callback function   In your theme s directory  locate or create a file called functions php and add the following in   lt  php      add filter  quot the content quot    quot plugin myContentFilter quot       function plugin myContentFilter  content             Take the existing content and return a subset of it     return substr  content  0  300         gt   The plugin myContentFilter   is a function you provide that will be called each time you request the content of a post type like posts pages via the content    It provides you with the content as an input  and will use whatever you return from the function for subsequent output or other filter functions  You can also use add filter   for other functions like the excerpt   to provide a callback function whenever the excerpt is requested  See the Wordpress filter reference docs for more details
