-

found code online , worked of sudden 1 day "fatal error: cannot use object of type stdclass array in.. functions.php" on line $count = absint( $json[0]->total_count );

function ds_post_like_count( $post_id ) {    // check transient   if ( ! ( $count = get_transient( 'ds_post_like_count' . $post_id ) ) ) {      // setup query arguments based on post permalink     $fql  = "select url, ";     //$fql .= "share_count, "; // total shares     //$fql .= "like_count, "; // total likes     //$fql .= "comment_count, "; // total comments     $fql .= "total_count "; // summed total of shares, likes, , comments (fastest query)     $fql .= "from link_stat url = '" . get_permalink( $post_id ) . "'";      // api call     $response = wp_remote_retrieve_body( wp_remote_get( 'https://api.facebook.com/method/fql.query?format=json&query=' . urlencode( $fql ) ) );      // if error in api call, stop , don't store transient     if ( is_wp_error( $response ) )       return 'error';      // decode json     **$json = json_decode( $response );**      // set total count     $count = absint( $json[0]->total_count );      // set transient expire every 30 minutes     set_transient( 'ds_post_like_count' . $post_id, absint( $count ), 30 * minute_in_seconds );    }   return absint( $count );  } /** facebook end  */  function ds_social_media_icons() {     // post id   $post_id = get_the_id(); ?>    <?php print_r($response) ?>   <div class="social-icons-wrap">     <ul class="social-icons">         <!-- facebook button-->         <li class="social-icon facebook">             <a onclick="javascript:popupcenter('https://www.facebook.com/sharer/sharer.php?u=<?php the_permalink(); ?>&amp;appid=xxx_your_facebook_app_id','facebook share', '540', '400');return false;" href="https://www.facebook.com/sharer/sharer.php?u=<?php the_permalink(); ?>&amp;appid=xxx_your_facebook_app_id" target="blank"><i class="fa fa-facebook"></i> share </a><span class="share-count"><?php echo ds_post_like_count( $post_id ); ?></span>         </li>         <!-- twitter button -->         <li class="social-icon twitter">             <a onclick="javascript:popupcenter('https://twitter.com/share?&amp;url=<?php the_permalink(); ?>&amp;text=<?php the_title(); ?>&amp;via=xxx_your_twitter_handle','tweet', '540', '400');return false;" href="https://twitter.com/share?&amp;url=<?php the_permalink(); ?>&amp;text=<?php the_title(); ?>&amp;via=xxx_your_twitter_handle" target="blank"><i class="fa fa-twitter"></i> tweet </a><span class="share-count"><?php echo ds_post_tweet_count( $post_id ); ?></span>         </li>            </ul>   </div><!-- .social-icons-wrap -->  <?php } /* don't delete closing tag */ ?>

to use output array, need set second parameter true. 

if( ! is_wp_error( $response )          && isset( $response['response']['code'] )                 && 200 === $response['response']['code'] )     {         $body = wp_remote_retrieve_body( $response );         $fb   = json_decode( $body );          if( ! isset( $fb->likes ) && isset( $fb->shares ) )         {             $fb->likes = $fb->shares;         }          if( isset( $fb->likes ) )         {             $myfblikes = sprintf( '%04s', (int) $fb->likes );             update_post_meta( $post->id, 'fb_likes', $myfblikes );        }     }
