让Facebook像计数一样

I have integrated Facebook Like into my website.Now i need to get/list the count of the Facebook like in the Admin panel of my website. Is there any way to get this done?Need suggestions.Thanks in advance.

In order to get the number of likes of any object using Facebook API, use a Facebook API of your choice and commands like this:

 https://graph.facebook.com/< your object id>/

You will receive a JSON object and you can extract the number of likes from it:

 {
 "id": "567454",
 "link": "http://www.facebook.com/pages/PHP-Developer/103146756409401",
 "likes": 250,
 "type": "page"
 }

More info on https://developers.facebook.com/docs/reference/api/

The more direct / updated link for this topic on facebook is

https://developers.facebook.com/docs/reference/api/page/

$url = 'http://graph.facebook.com/PAGE_OR_APP_ID';
echo '['.$url.']: '.json_decode(file_get_contents($url))->{'likes'};

function fbLikeCount($appid,$appsecret){
//Construct a Facebook URL
$json_url ='https://graph.facebook.com/'.$appid.'?access_token='.$appsecret;
$json = file_get_contents($json_url);
$json_output = json_decode($json);

//Extract the likes count from the JSON object
if($json_output->likes){
    return $likes = $json_output->likes;
}else{
    return 0;
}

}

Facebook - <?php echo fbLikeCount('app/page id here','token here'); ?>

You can achieve that using the Graph API (v3)

function checkFacebookReactions($url){
    $access_token = 'YOUR-FACEBOOK-TOKEN'; // Generate a Facebook Token first

    $api_url = 'https://graph.facebook.com/v3.0/?id=' . urlencode( $url ) . '&fields=engagement&access_token=' . $access_token;
    $fb_connect = curl_init(); // initializing
    curl_setopt( $fb_connect, CURLOPT_URL, $api_url );
    curl_setopt( $fb_connect, CURLOPT_RETURNTRANSFER, 1 ); // return the result, do not print
    curl_setopt( $fb_connect, CURLOPT_TIMEOUT, 20 );

    $json_return = curl_exec( $fb_connect ); // connect and get json data
    curl_close( $fb_connect ); // close connection
    $body = json_decode( $json_return );

    // Print each key values, if needed
    foreach($body->engagement as $k=>$v){
        echo $k .": " .$v ."<br>";
    }

    $count = $body->engagement->reaction_count; // Return only reactions (likes + other reactions)
    return $count; 
}

$url = "REPLACE-WITH-YOUR-URL"; // The url you want to fetch details from
checkFacebookReactions($url);

First, you will need to generate a Facebook token. You can fin plenty of resources that explain how to get a token. This one will do the trick: https://elfsight.com/blog/2017/10/how-to-get-facebook-access-token
