Display recent posts based on post size using IF STATEMENT

Question

I have a sidebar in wordpress that shows my recent posts. The php code that does this is simply:

$recent_posts = wp_get_recent_posts(array("numberposts"=>5));

I would like to include an IF statement to say:

"If the wordpress post is more than 100 words, display 10 recent posts, else display 5"

I will work out the relevant numbers etc. once I know how this is achieved.

You can use the global $post to inspect the length of the post_content and then set the $numberposts accordingly.

global $post;
$numberposts = 1; // default number of posts
if ( !empty($post) ){
    $len = strlen( $post->post_content );
    // change $numberposts based on length of $post->post_content
    if ( $len < 300 ){
      $numberposts = 8;
    } elseif ( $len < 500 ){
      $numberposts = 5;
    } elseif ( $len < 800 ){
      $numberposts = 3;
    } else {
      $numberposts = 1;
    }
}
$recent_posts = wp_get_recent_posts(array("numberposts"=>$numberposts));
