Multiple excerpt lengths in wordpress

by

How about…

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;
}

then in your template code you just use..

<?php echo excerpt(25); ?>
