Use PHP to develop a second-hand recycling website to implement full-text search function

In second-hand recycling websites, users often need to search for a specific item or keyword to find second-hand products that meet their needs. Developing a website with full-text search capabilities can help users find what they need quickly. This article will introduce how to use PHP language to achieve this function and provide code examples.

1. Establish a database

First, you need to establish a database to store the second-hand product information released by users. Suppose we have created a database named "goods", which contains a table named "goods_table", which contains the following fields:

id: unique identifier of the product, using an auto-increasing integer type ;
title: Product title, using VARCHAR type;
description: Product description, using TEXT type.

2. Create a search page

First, we need to create a search page for users to enter keywords to search. You can create a file named "search.php" and write the following code in the file:

<html>
<head>
<title>二手回收网站-搜索</title>
</head>
<body>
<h1 id="二手回收网站搜索">二手回收网站搜索</h1>
<form method="GET" action="result.php">
<input type="text" name="keyword" placeholder="请输入关键词">
<input type="submit" value="搜索">
</form>
</body>
</html>

3. Query the database

Next, we need to write PHP code to query the database and Return matching results. Create a file called "result.php" and write the following code:

<?php
// 连接数据库
$servername = "localhost";
$username = "root";
$password = "";
$database = "goods";

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

// 获取用户输入的关键词
$keyword = $_GET['keyword'];

// 查询数据库
$sql = "SELECT * FROM goods_table WHERE MATCH(title, description) AGAINST('$keyword' IN BOOLEAN MODE)";
$result = $conn->query($sql);

// 打印搜索结果
if ($result->num_rows > 0) {
  while($row = $result->fetch_assoc()) {
    echo "商品ID: " . $row["id"]. "<br>标题: " . $row["title"]. "<br>描述: " . $row["description"]. "<br><br>";
  }
} else {
  echo "未找到匹配的商品";
}

$conn->close();
?>

In this code, we first connect to the database named "goods". Then, obtain the keywords entered by the user through the GET method. Next, we use MySQL's FULLTEXT index to perform full-text search and return matching results. Finally, print out the search results through a loop.

So far, we have implemented a second-hand recycling website with full-text search function. Users can enter keywords on the search page, and the website will query the database based on the keywords and return matching product information.

Summary:

Through PHP language and MYSQL database, we can easily implement a second-hand recycling website with full-text search function. Through this function, users can quickly find the second-hand products they need. I believe the above code examples can help you develop an efficient second-hand recycling website.
