How to get Google +1 count for current page in PHP?

Question

I want to get count of Google +1s for current web page ? I want to do this process in PHP, then write number of shares or +1s to database. That's why, I need it. So, How can I do this process (getting count of +1s) in PHP ?
Thanks in advance.

Answer 1

This one works for me and is faster than the CURL one:

function getPlus1($url) {
    $html =  file_get_contents( "https://plusone.google.com/_/+1/fastbutton?url=".urlencode($url));
    $doc = new DOMDocument();   $doc->loadHTML($html);
    $counter=$doc->getElementById('aggregateCount');
    return $counter->nodeValue;
}

also here for Tweets, Pins and Facebooks

function getTweets($url){
    $json = file_get_contents( "http://urls.api.twitter.com/1/urls/count.json?url=".$url );
    $ajsn = json_decode($json, true);
    $cont = $ajsn['count'];
    return $cont;
}

function getPins($url){
    $json = file_get_contents( "http://api.pinterest.com/v1/urls/count.json?callback=receiveCount&url=".$url );
    $json = substr( $json, 13, -1);
    $ajsn = json_decode($json, true);
    $cont = $ajsn['count'];
    return $cont;
}

function getFacebooks($url) { 
    $xml = file_get_contents("http://api.facebook.com/restserver.php?method=links.getStats&urls=".urlencode($url));
    $xml = simplexml_load_string($xml);
    $shares = $xml->link_stat->share_count;
    $likes  = $xml->link_stat->like_count;
    $comments = $xml->link_stat->comment_count; 
    return $likes + $shares + $comments;
}

Note: Facebook numbers are the sum of likes+shares and some people said plus comments (I didn't search this yet), anyway use the one you need.

This will works if your php settings allow open external url, check your "allow_url_open" php setting.

Hope helps.

function get_plusones($url) {
  $curl = curl_init();
  curl_setopt($curl, CURLOPT_URL, "https://clients6.google.com/rpc");
  curl_setopt($curl, CURLOPT_POST, 1);
  curl_setopt($curl, CURLOPT_POSTFIELDS, '[{"method":"pos.plusones.get","id":"p","params":{"nolog":true,"id":"' . $url . '","source":"widget","userId":"@viewer","groupId":"@self"},"jsonrpc":"2.0","key":"p","apiVersion":"v1"}]');

  curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
  $curl_results = curl_exec ($curl);
  curl_close ($curl);
  $json = json_decode($curl_results, true);
  return intval( $json[0]['result']['metadata']['globalCounts']['count'] );
}

The cURL and API way listed in the other posts here no longer works.

There is still at least 1 method, but it's ugly and Google clearly doesn't support it. You just rip the variable out of the JavaScript source code for the official button with a regular expression:

function shinra_gplus_get_count( $url ) {
    $contents = file_get_contents( 
        'https://plusone.google.com/_/+1/fastbutton?url=' 
        . urlencode( $url ) 
    );

    preg_match( '/window\.__SSR = {c: ([\d]+)/', $contents, $matches );

    if( isset( $matches[0] ) ) 
        return (int) str_replace( 'window.__SSR = {c: ', '', $matches[0] );
    return 0;
}

The next PHP script works great so far for retrieving Google+ count on shares and +1's.

$url = 'http://nike.com';
$gplus_type = true ? 'shares' : '+1s';

/**
 * Get Google+ shares or +1's.
 * See out post at stackoverflow.com/a/23088544/328272
 */
function get_gplus_count($url, $type = 'shares') {
  $curl = curl_init();

  // According to stackoverflow.com/a/7321638/328272 we should use certificates
  // to connect through SSL, but they also offer the following easier solution.
  curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

  if ($type == 'shares') {
    // Use the default developer key AIzaSyCKSbrvQasunBoV16zDH9R33D88CeLr9gQ, see
    // tomanthony.co.uk/blog/google_plus_one_button_seo_count_api.
    curl_setopt($curl, CURLOPT_URL, 'https://clients6.google.com/rpc?key=AIzaSyCKSbrvQasunBoV16zDH9R33D88CeLr9gQ');
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, '[{"method":"pos.plusones.get","id":"p","params":{"nolog":true,"id":"' . $url . '","source":"widget","userId":"@viewer","groupId":"@self"},"jsonrpc":"2.0","key":"p","apiVersion":"v1"}]');
    curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
  }
  elseif ($type == '+1s') {
    curl_setopt($curl, CURLOPT_URL, 'https://plusone.google.com/_/+1/fastbutton?url='.urlencode($url));
  }
  else {
    throw new Exception('No $type defined, possible values are "shares" and "+1s".');
  }

  $curl_result = curl_exec($curl);
  curl_close($curl);

  if ($type == 'shares') {
    $json = json_decode($curl_result, true);
    return intval($json[0]['result']['metadata']['globalCounts']['count']);
  }
  elseif ($type == '+1s') {
    libxml_use_internal_errors(true);
    $doc = new DOMDocument();
    $doc->loadHTML($curl_result);
    $counter=$doc->getElementById('aggregateCount');
    return $counter->nodeValue;
  }
}

// Get Google+ count.
$gplus_count = get_gplus_count($url, $gplus_type);
