问题描述

这是我的代码:

$v = $conn->query("SELECT * FROM `categories` WHERE `Link`!=''");


while($vrowi = mysql_fetch_array($v, MYSQLI_ASSOC))

{

$url = $vrowi['Link'];
$Cat = $vrowi['id'];
}

while循环不起作用.你能告诉我错误在哪里吗?预先感谢！

The while loop isn't working. Can you please tell me where the mistake is? Thanks in advance!

推荐答案

您正在将面向对象的MySQLi代码与一种功能性方法混合在一起，并且需要选择其中一种.确切地说，解决方案是这样的:

You're mixing object-oriented MySQLi code with a functional approach, and need to choose either one or the other. In your exact, the solution is this:

$v = $conn->query("SELECT * FROM `categories` WHERE `Link` != '';");

while ($vrowi = $v->fetch_assoc()) {
    $url = $vrowi['Link'];
    $Cat = $vrowi['id'];
}
