解决Typecho下文章cid、分类和标签mid不连续的问题(php7.2可用)

<?php
/**
* Typecho重新排列分文章cid让他连续
*/
<?php

// 设置数据库参数
$hostname_blog = "localhost";
$database_blog = "数据库名";
$username_blog = "数据库用户名";
$password_blog = "数据库密码";

// 连接到数据库
$blog = mysqli_connect($hostname_blog, $username_blog, $password_blog, $database_blog) or die(mysqli_connect_error());

// 设置计数器的初始值
$no = 1;

// 定义一个函数来更新文章cid
function change_id($cid)
{
    global $no, $blog;

    // 更新文章cid，并更新与类别、标签、自定义字段和评论的关系
    mysqli_query($blog, "UPDATE typecho_contents SET cid = $no WHERE cid = $cid");
    mysqli_query($blog, "UPDATE typecho_relationships SET cid = $no WHERE cid = $cid");
    mysqli_query($blog, "UPDATE typecho_comments SET cid = $no WHERE cid = $cid");

    $no = $no + 1;
}

// 从数据库中选择所有文章cid，按其 cid 排序
$query_postRecord = "SELECT cid FROM typecho_contents ORDER BY cid ASC";
$result = mysqli_query($blog, $query_postRecord);

// 循环浏览文章并更新其 cid
while ($row = mysqli_fetch_assoc($result)) {
    change_id($row['cid']);
}

// 重置文章 cid 的自动递增值
mysqli_query($blog, "ALTER TABLE typecho_contents AUTO_INCREMENT = $no");

echo 'ok';
