致命錯誤：調用未定義函數mysqli_master_query（）

Question

查詢我的數據庫時遇到問題。我收到以下錯誤：

Fatal error: Call to undefined function mysqli_master_query() in /home/**/**/**/edit/add.php on line 4 

這是我的PHP代碼..

<?php 
    $db = mysqli_connect("localhost","XXX","XXX","XXX") or die(mysql_error()); 

    if(mysqli_master_query($db, "UPDATE users SET order =1 WHERE id =1")){ 
     echo "Y"; 
    }else{ 
     echo "N"; 
    } 
?> 

Answer 1

mysqli_master_query()

This function has been DEPRECATED and REMOVED as of PHP 5.3.0. 

Answer 2

哪個版本您使用的？

mysqli_master_query（）函數從PHP 5.3.0開始已經被取消和刪除。
