 * Hi this is probably a very basic question, but here it goes. I’m displaying a
   list of related posts in my single.php and I’m showing the title and the excerpt
   and a custom field image. I would like to cut the length of the excerpt to one
   sentence for each related item.
 * By using preg_split as suggested here:
    [http://php.about.com/od/advancedphp/ss/php_preg_5.htm](http://php.about.com/od/advancedphp/ss/php_preg_5.htm)
 * I have managed to return an array that contains each sentence. I have used this
   code:
 *     ```
       <?php
       $str = $post->post_excerpt;
       $sentances= preg_split('/\./', $str, -1 , PREG_SPLIT_NO_EMPTY);
       print_r($sentances);
       ?>
       ```
   
 * This particular code, returns something like this:
 * > Array ( [0] => Maecenas fermentum semper purus [1] => Fusce vitae tortor [2]
   > => In laoreet ante ornare metus lobortis pretium [3] => Suspendisse eu libero[
   > 4] => Suspendisse facilisis [5] => Phasellus convallis, purus in imperdiet 
   > condimentum, nisi orci gravida ligula, eu pellentesque odio risus quis risus[
   > 6] => Aenean vitae pede at enim imperdiet varius [7] => Vivamus sodales feugiat
   > est [8] => Nulla lobortis consectetuer magna )
 * I would like to only echo the very first sentence, how would i go about doing
   that?
