The second-hand recycling website developed by PHP provides fast and free publishing functions

With the continuous development of technology and the improvement of consumption levels, people's lives have become more abundant and diverse. However, the problem that comes with it is the increase in waste, especially second-hand goods. If these second-hand goods can be effectively recycled, they can not only reduce resource waste, but also provide convenience and cost-saving opportunities for others. Therefore, it is of great significance to develop a second-hand recycling website.

This article will use PHP as the development language to introduce a development idea for a Web-based second-hand recycling website, and provide a code example of a quick and free release function to help readers better understand and practice.

1. Development ideas
1. Requirements analysis: First, we need to clarify the functional requirements of the second-hand recycling website. Generally speaking, a website should have user registration and login functions, second-hand product publishing and search functions, a trading system, and user reviews and suggestions. Carry out system design and module analysis according to specific needs.

2. Database design: Design a reasonable database structure based on the functional modules obtained through demand analysis. Commonly used data tables include user tables, product tables, transaction tables, etc. For the convenience of demonstration, we only selected some major data tables for examples.

3.UI design: Design an intuitive and concise user interface based on user experience principles. The homepage of the website should clearly display the classification of second-hand goods, as well as the user login and registration entrance, to facilitate user operations.

4. Back-end development: Use PHP as the development language, combined with the MySQL database, to realize the functions of the website. It mainly includes the background logic code for user registration, login, product release, search, transaction and other functions.

2. Code example of free publishing function
In second-hand recycling websites, free publishing function is one of the important ways for users to publish second-hand products. Below we provide a simple sample code to demonstrate how to implement this function.

1. First, create a file named post.php as the free publishing page. Add a form to the page for users to fill in publishing information.

<form action="post.php" method="post">
    <input type="text" name="title" placeholder="请输入商品标题">
    <textarea name="description" placeholder="请输入商品描述"></textarea>
    <input type="submit" value="发布">
</form>

2. In the post.php file, add PHP code to handle the user's post request and save the data to the database.

<?php
// 连接数据库
$servername = "localhost";
$username = "root";
$password = "123456";
$dbname = "secondhand";

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

// 处理用户的发布请求
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $title = $_POST["title"];
    $description = $_POST["description"];

    // 插入数据到商品表
    $sql = "INSERT INTO goods (title, description) VALUES ('$title', '$description')";

    if ($conn->query($sql) === TRUE) {
        echo "发布成功";
    } else {
        echo "发布失败: " . $conn->error;
    }
}

$conn->close();
?>

The above code realizes the free publishing function by obtaining the form data submitted by the user and inserting the data into the product table using SQL statements.

3. Summary
Through the above code examples, we demonstrate how to use PHP to develop a second-hand recycling website that provides fast and free publishing capabilities. Of course, website development also involves many other functions and details, such as user registration, login, product search, trading system, etc. This article only introduces the implementation method of one of the functions. Readers can further develop and improve it according to actual needs.

The development of second-hand recycling websites has a positive role in promoting environmental protection and resource conservation. I hope that through the introduction of this article, more people can be inspired to participate in the recycling of second-hand goods and jointly contribute to environmental protection. At the same time, I also hope that this article will be helpful to readers and can apply relevant knowledge and skills in actual development.
