   Hi there,
   I'm trying to code a function (in functions.php) that returns me the number of characters in the excerpt, I think this example will illustrates better the scenario.

   In functions.php
   

   function custom_excerpt($excerpt_num){
   	$default_excerpt = get_the_content();
   	$new_default_excerpt = explode(' ', $default_excerpt, $excerpt_num);
   	array_pop($new_default_excerpt);
   	$new_excerpt = implode(' ', $new_default_excerpt);
   	return $new_excerpt;
   }

   In the template (inside a loop):
   <?php custom_excerpt(15) ?>
   Here I wanted to show an excerpt with 15 characters, but it's not returning nothig.

   Any solutions? thanks!

   function custom_excerpt($excerpt_num){
   	$default_excerpt = get_the_content();
   	/*$new_default_excerpt = explode(' ', $default_excerpt, $excerpt_num);
   	array_pop($new_default_excerpt);
   	$new_excerpt = implode(' ', $new_default_excerpt);*/
           $new_excerpt = substr($default_excerpt, 0, $excerpt_num);
   	return $new_excerpt;
   }

   Try this.
