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.
