在这里，您会看到我为“fb_comment_count”和“my_post_gallery”设置了两个功能：Pastebin。
在第123行附近，你会看到我正在使用“fb_comment_count”。问题是生成的标记不会将注释计数放在那些span标记内，而是放在其他地方。
以下是生成的标记，以显示我的意思。所有评论计数（a标记）都被推到顶部，span标记（<span class="comment-number"></span>）为空。任何人都可以帮我弄清楚为什么会这样吗？

答案 0 :(得分：1)
在PHP函数中使用return而不是echo。所以，对于示例，而不是在第26行：
echo $comments;
将其更改为：
return $comments;
对于echo的其他行也是如此。
