函数将html放在预期的span标签之外

Here you'll see I have two functions set up for "fb_comment_count" and "my_post_gallery": Pastebin.

Around line 123, you'll see that I am using "fb_comment_count". The trouble is that the generated markup does not place the comment count number within those span tags but rather somewhere else.

Below is the generated markup to show you what I mean. All of the comment counts (the a tags) are pushed to the top and the span tags (<span class="comment-number"></span>) are empty. Can anyone help me figure out why this happens?

    In your PHP function use return instead of echo. so, for example, instead of having this on line 26:

    echo $comments;
    

    change it to:

    return $comments;
    

    Same thing goes for other lines with echo.
