如何将mysql_fetch_assoc更改为mysqli

Question

如何将此变为mysqli？

// add meta_key to the query 
$get_user_data = mysql_query("SELECT `meta_value`,`meta_key` FROM `table` WHERE `user_id` = $user_id", $link); 

// use _assoc instead of _array, we do not need the numerical indexes. 
while($row=mysql_fetch_assoc($get_user_data)){ 
    $userdata[$row['meta_key']] = $row['meta_value']; 
}

只需简单的修改，你必须在你的代码所做的：

// add meta_key to the query 
$get_user_data = mysqli_query($link,"SELECT `meta_value`,`meta_key` FROM `table` WHERE `user_id` = $user_id"); 

// use _assoc instead of _array, we don't need the numerical indexes. 
while($row=mysqli_fetch_assoc($get_user_data)) 
{ 
    $userdata[$row['meta_key']] = $row['meta_value']; 
}
