Php 主机中未检索用户表数据

我使用了以下脚本，从WordPress上的USER表中检索用户ID.此脚本工作在本地服务器和所有其他服务器上.但这在Hostinger服务器中不起作用.

为什么这在Hostinger不起作用？

只有这是print_r($query);，但找不到$userid=$query[0][ID]; ID

<?php
    if (sanitize_text_field($_GET['ven_search_title']) && sanitize_text_field ($_GET['ven_search_title']))
    {
        $ven_search_title = sanitize_text_field($_GET['ven_search_title']);
    }

    global $wpdb;
    $table = $wpdb->prefix . 'users'; 
    $query = $wpdb->get_results("SELECT * FROM $table WHERE user_nicename LIKE '%".$ven_search_title."%'", ARRAY_A);

    
    if($query){
 
    echo "<pre>";
    print_r ($query);
    echo "</pre>";  
 
    $userid=$query[0][ID];
    
    echo "<pre>";
    print_r ($query[0][ID]);
    echo "</pre>";  
?>     
<?php $user=get_userdata($userid)?>
    <a href="<?php echo bloginfo('url').'/store/'.$user->user_nicename; ?>">
    <div class="store-wrappers"> 
        <div class="seller-avatar"><?php echo get_avatar($userid) ?></div>
        <div class="storebody">
            <div class="search_title"><span>Store Name:</span> <?php echo $user->user_nicename; ?> </div> 
        </div>   
    <div style="clear:both;"></div>
