I have both default WordPress and Facebook comments enabled on my WordPress blog.

Of course, my theme only shows comment number of WordPress comments.

What I need is a way to retrieve the number of comments from Facebook comments box on every post and then add it to the comments number of WordPress comments.

I can not use 

```
<fb:comments-count href=http://example.com/></fb:comments-count> 

```

because it uses javascript.
I am not proficient in php so any help would be great.
I know I can use graph api, but don't know how to get comments number and add it to WordPress count.

Thank you in advance!
