Code sample:

<?php

// 连接数据库
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 查询所有用户
$sql = "SELECT id, username, email FROM users";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // 输出每个用户的信息
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - 用户名: " . $row["username"]. " - 邮箱: " . $row["email"]."<br>";
    }
} else {
    echo "0 结果";
}
$conn->close();

?>

The above code sample demonstrates how to connect to the database and query all users' information, and output it to the page. This is one of the common operations in the mall system. PHP provides flexible and concise syntax, allowing developers to easily implement these functions.
