我正在wordpress中使用WP REST API插件，希望使用for-each循环遍历json数据，但是当我var\\u转储存储json数据的变量时，它会给我一个错误。

“分析错误：语法错误，在C:\\wamp\\www\\public\\u html\\wp content\\themes\\raj\\template-wiki.php的第22行出现意外的\'->\'（T\\u OBJECT\\u操作符）”

<?php $json = lusso_posts(); ?>

<?php var_dump($json); ?>

<?php echo ($json->wp-json->posts[1]->ID); ?>

我认为“wp-json”与“->”这个符号相冲突，因为当我从“wp-post”中删除“-”时，错误消失了，但什么也没有显示。

LUSSO函数的代码

`函数lusso\\u posts（）{

  // Do we have this information in our transients already?
  $transient = get_transient( \'lusso_posts\' );

  // Yep!  Just return it and we\'re done.
  if( ! empty( $transient ) ) {

    // The function will return here every time after the first time it is   run, until the transient expires.
    return $transient;

  // Nope!  We gotta make a call.
  } else {

    // We got this url from the documentation for the remote API.
    $url = \'http://localhost/database2/wp-json/posts/\';

    $body =  wp_remote_retrieve_body(wp_remote_get($url));

    $json = json_decode($body);


    // Call the API.
    //$out = wp_remote_get( $url, $args );

    // Save the API response so we don\'t have to call again until  tomorrow.
    set_transient( \'lusso_posts\', $json, DAY_IN_SECONDS );

    // Return the list of subscribers.  The function will return here the first time it is run, and then once again, each time the transient expires.
    return $json;

  }

}`

任何帮助都将不胜感激。

谢谢

$json = lusso_posts();
#var_dump( $json );
#die();

foreach( $json as $post ) { 
    $titles = $post->title;
    $images = $post->featured_image->guid;
    ?>
    <div class="lusso-posts">
        <div class="image-container"><img src="<?php echo $images; ?>" />    </div>
        <h4><?php echo $titles; ?></h4>
    </div>
