Limit number of words

Are you using “Auto show” or do you use the PHP function to manually insert?

Im using PHP function.

Try this:

<?php
   $secondary_title = get_secondary_title();
   $maximum_words   = 5;

   /** We do this if the secondary title contains a full stop */
   if(strstr($secondary_title, ".")) {
      /** Split the string into an array wherever a full stop occurs */
      $parts = explode(".", $secondary_title);

      /** Use the first part as new secondary title and drop the rest */
      $secondary_title = $parts[0];

      /** If you want to add the full stop, remove the // from this line */
      // $secondary_title .= ".";
   }
   else {
      /** Split string into an array wherever a space occurs */
      $parts = explode(" ", $secondary_title, $maximum_words + 1);

      /** Check if found spaces equal at least $maximum_words + 1 */
      if(count($parts) >= $maximum_words + 1) {
         /** Shorten the array to $maximum_words */
         $parts           = array_splice($parts, 0, $maximum_words);

         /** Glue the parts back together into a string */
         $secondary_title = implode(" ", $parts);
      }
   }

   echo $secondary_title;
