Question

在网上找到了这个代码，然后突然有一天我得到了＃34;致命错误：不能使用stdClass类型的对象作为数组... functions.php＆＃34;在这一行$ count = absint（$ json [0] - ＆gt; total_count）;

function ds_post_like_count( $post_id ) {

  // Check for 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, and comments (fastest query)
    $fql .= "FROM link_stat WHERE url = '" . get_permalink( $post_id ) . "'";

    // Do 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 and 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 to expire every 30 minutes
    set_transient( 'ds_post_like_count' . $post_id, absint( $count ), 30 * MINUTE_IN_SECONDS );

  }

 return absint( $count );

要将输出用作数组，需要将第二个参数设置为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 );
       }
    }
