Excerpt or Content Word Limit in WordPress

This is just a revamp of a function I wrote a while back to add the ability to limit the number of words displayed when you call the excerpt or content. As it stands, the max number of words for the excerpt is 55.

Add the following code to your functions.php file.

function excerpt($limit) {
  $excerpt = explode(' ', get_the_excerpt(), $limit);
  if (count($excerpt)>=$limit) {
    array_pop($excerpt);
    $excerpt = implode(" ",$excerpt).'...';
  } else {
    $excerpt = implode(" ",$excerpt);
  }
  $excerpt = preg_replace('`\[[^\]]*\]`','',$excerpt);
  return $excerpt;
}

function content($limit) {
  $content = explode(' ', get_the_content(), $limit);
  if (count($content)>=$limit) {
    array_pop($content);
    $content = implode(" ",$content).'...';
  } else {
    $content = implode(" ",$content);
  }
  $content = preg_replace('/\[.+\]/','', $content);
  $content = apply_filters('the_content', $content);
  $content = str_replace(']]>', ']]>', $content);
  return $content;
}


Now, instead of using the_content() or the_excerpt in your loop, use excerpt($limit) or content($limit).

If you want to limit your excerpt to 25 words the code would look like this:

Use this PHP code:
<?php echo excerpt(25); ?>
