Get the count of tweets, likes and +1's for a URL. Saved from this repo - https://github.com/whyisjake/Social-Stats - but I didn't feel it deserved an actual repo so I saved it as a gist, and also added a function that returns all three stats for you. Currently relies on some WordPress functions, will need to alter that at some point.

social-stats.php

<?php
function make_get_tweets( $url ) {
    $json_string = wpcom_vip_file_get_contents( 'http://urls.api.twitter.com/1/urls/count.json?url=' . $url );
	$json = json_decode($json_string, true);

	return intval( $json['count'] );
}

function make_get_likes( $url ) {
	$json_string = wpcom_vip_file_get_contents('http://graph.facebook.com/?ids=' . $url);
	$json = json_decode($json_string, true);

	return intval( $json[$url]['shares'] );
}

function make_get_plusones( $url ) {
	$args = array(
			'method' => 'POST',
			'headers' => array(
				// setup content type to JSON
				'Content-Type' => 'application/json'
			),
			// setup POST options to Google API
			'body' => json_encode(array(
				'method' => 'pos.plusones.get',
				'id' => 'p',
				'method' => 'pos.plusones.get',
				'jsonrpc' => '2.0',
				'key' => 'p',
				'apiVersion' => 'v1',
				'params' => array(
					'nolog'=>true,
					'id'=> $url,
					'source'=>'widget',
					'userId'=>'@viewer',
					'groupId'=>'@self'
				)
			 )),
			 // disable checking SSL sertificates
			'sslverify'=>false
		);

	// retrieves JSON with HTTP POST method for current URL
	$json_string = wp_remote_post( "https://clients6.google.com/rpc", $args );

	if ( is_wp_error( $json_string ) ) {
		// return zero if response is error
		return "0";
	} else {
		$json = json_decode( $json_string['body'], true );
		// return count of Google +1 for requsted URL
		return intval( $json['result']['metadata']['globalCounts']['count'] );
	}
}

function make_get_all( $url ) {
    return array(
        'tweets' => make_get_tweets( $url ),
        'likes' => make_get_likes( $url ),
        'plusones' => make_get_plusones( $url )
    );
}
