如何在Wordpress插件的PHP中遍历JSON数据

Question

我正在构建一个调用第三方API的插件。 我正在取回数据，但看起来有点时髦，我无法迭代和操纵数据以显示在页面上。

我正在使用此函数来调用正在运行的API ...

function herocreative_rentcafe_get_data( $herocreative_companycode, $herocreative_propertycode ) {

    $json_feed_url = 'https://api.rentcafe.com/rentcafeapi.aspx?requestType=floorplan&companyCode=' . $herocreative_companycode . '&propertyCode=' . $herocreative_propertycode ;
    $args = array( 'timeout' => 120 );

    $json_feed = wp_remote_get( $json_feed_url, $args );

    $herocreative_data = json_decode( $json_feed['body'] );

    return $herocreative_data;

} 

我正在使用此代码来迭代响应...

   <?php for( $i = 0; $i < count($herocreative_data); $i++ ): ?>
    <li>
        <ul>
            <li>
                <?php echo $herocreative_data->{'AvailableUnitsCount'}[$i]; ?>              
            </li>
        </ul>                                   
    </li>                               
    <?php endfor; ?>

返回的数据是这样的：

您需要做的是在数组上进行foreach循环，然后每次出现都包含一个对象地址，因此

<?php 
foreach ( $herocreative_data as $data) : 
?>
<li>
    <ul>
        <li>
            <?php echo $data->AvailableUnitsCount; ?>              
        </li>
    </ul>                                   
</li>                               
<?php 
endforeach; 
?>
