Title: Detailed explanation and operation steps of how to modify PHPCMS username

With the increasing development of the Internet, website construction has become an important way for many companies and individuals to showcase themselves. As an open source content management system, PHPCMS has been widely used in website construction. In the process of using PHPCMS, sometimes we encounter situations where we need to modify the user name. This article will introduce in detail how to modify the PHPCMS user name, including specific steps and code examples.

1. PHPCMS user name modification method

PHPCMS does not provide the function of modifying the user name by default, but we can realize the function of modifying the user name by writing a simple code. The specific implementation process is as follows:

Step 1: Find the user modification page

First, we need to find the user management page in the PHPCMS background, usually located at "Members-->Member Management". In the member management page, you can find the user whose username needs to be modified and click to enter its detailed information page.

Step 2: Edit user name

In the user details page, we can find the user name input box and enter the user name that needs to be modified into the input box.

Step 3: Save modifications

After modifying the user name, be sure to click the Save button to save the modified user name to the database.

2. Specific code example

The following is a simple PHP code example for modifying the username of the PHPCMS user:

<?php
// 连接PHPCMS数据库
$link = mysqli_connect('localhost', 'root', 'password', 'phpcms');
if (!$link) {
    die('Could not connect: ' . mysqli_error());
}

// 需要修改用户名的用户ID
$user_id = 1;
// 新的用户名
$new_username = 'new_username';

// 更新用户名
$sql = "UPDATE `phpcms_member` SET `username` = '$new_username' WHERE `userid` = $user_id";
if (mysqli_query($link, $sql)) {
    echo "用户名修改成功";
} else {
    echo "Error updating record: " . mysqli_error($link);
}

// 关闭数据库连接
mysqli_close($link);
?>

In the above code, first pass mysqli connects to the PHPCMS database, then specifies the user ID and new user name that need to be modified, and finally executes an update statement to save the new user name to the database.
