The second-hand recycling website uses the real-name authentication function developed by PHP
With the gradual development of the second-hand recycling market, people pay more and more attention to the issues of safety and credibility when trading second-hand goods. In order to increase user trust, many second-hand recycling websites have begun to introduce real-name authentication functions. This article will introduce how to use PHP to develop a real-name authentication function to improve the user credibility and security of second-hand recycling websites.
First, we need to create a database to store the user's real-name authentication information, which can be stored using a MySQL database. The following is an example of the structure of a simple user table:
CREATE TABLE `user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(255) NOT NULL, `realname` varchar(255) NOT NULL, `id_card` varchar(255) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
When a user registers, we need to collect the real name and ID number from the user and store them in the database. The following is a sample code for a simple registration page:
<!DOCTYPE html>
<html>
<head>
<title>用户注册</title>
</head>
<body>
<h1>用户注册</h1>
<form action="register.php" method="post">
<label for="username">用户名：</label>
<input type="text" name="username" required><br>
<label for="realname">真实姓名：</label>
<input type="text" name="realname" required><br>
<label for="id_card">身份证号码：</label>
<input type="text" name="id_card" required><br>
<input type="submit" value="注册">
</form>
</body>
</html>Next, we write the registration handler register.php to store the user's real-name authentication information in the database. The following is a simple sample code:
<?php
$username = $_POST['username'];
$realname = $_POST['realname'];
$id_card = $_POST['id_card'];
// 连接数据库
$servername = "localhost";
$username_db = "your_username";
$password_db = "your_password";
$dbname = "your_database";
$conn = new mysqli($servername, $username_db, $password_db, $dbname);
// 检查数据库连接是否成功
if ($conn->connect_error) {
die("数据库连接失败: " . $conn->connect_error);
}
// 将实名认证信息插入数据库
$sql = "INSERT INTO user (username, realname, id_card) VALUES ('$username', '$realname', '$id_card')";
if ($conn->query($sql) === TRUE) {
echo "注册成功";
} else {
echo "注册失败";
}
// 关闭数据库连接
$conn->close();
?>Through the above code, we successfully stored the user's real-name authentication information in the database. When the user logs in again, we can query the user's real-name authentication information in the database to verify the user's authenticity. In this way, users can enjoy more credit and security in second-hand recycling transactions.
To sum up, using PHP to develop the real-name authentication function can effectively improve the user trust and security of second-hand recycling websites. We hope that the sample code provided in this article can be helpful in developing the real-name authentication function.
