Hey Andrew,

First off, thanks for this incredibly useful include. I looked for hours to find something like this where a bunch of use cases are already done for you :) very helpful!

Just a couple things I noticed when using the code here that will help future users.

In the comment area at the top the arrays for YouTube are missing the network arguments and the = signs should be => instead. Like so:

$youtube_likes = social_count('youtube', array(
    'channel' => 'your_youtube_channel_name'
));
 
$youtube_subscribers = social_count('youtube', array(
    'channel' => 'your_youtube_channel_name',
    'data' => 'subscriberCount'
));

Otherwise PHP doesn't read it as an array and sends a parse error.

Hope this makes it to your next revision round!

Thanks again,

James~

Hey Andrew,
I'm working on a Google Plus code right now. Seems like you code returns nothing. I inspected G+ profile page and changed regex to /class="Myb j0c">([0-9,]+)</i (currently count number can be found in <span class="Myb j0c">1,391</span> tag). Still trying to make it work.

@jfbuildstuff Thanks, updated in revision 11

@ihorvorotnov Unfortunately G+ is the least reliable of the networks as we're relying on an HTML scrape rather than a proper API. Did you get it working in the end?

@ihorvorotnov Google now has a G+ API, so today I updated the code to revision 13 which uses the official API rather than scraping the data which is much more reliable.

Facebook now requires authentication for fetching likes, revision 14 supports this.

Upgraded YouTube API to v3
