Use PHP and Coreseek to implement efficient e-commerce shopping search function

In today's e-commerce industry, search functions are widely used in shopping websites and applications. In order to provide a better user experience, an efficient search function is crucial. This article will introduce how to use PHP and Coreseek to implement an efficient e-commerce shopping search function, and provide relevant code examples.

1. Introduction to Coreseek

Coreseek is an open source full-text search engine that is expanded and optimized based on the Sphinx full-text search engine. Coreseek has the characteristics of high performance, high stability and scalability, and is widely used in various websites and applications.

2. Install and configure Coreseek

  1. Install Sphinx and Coreseek

First, we need to install the Sphinx search engine and Coreseek extension. You can download the latest stable version from the official website and install and configure it according to the official documentation.

  1. Configuring the index file

Before using Coreseek, we need to configure an index file to specify the data source to be searched. You can store the data you need to search in a database and use the tools provided by Coreseek to generate index files.

3. Use PHP to perform search operations with Coreseek

  1. Connect to Coreseek

In PHP, we can use the SphinxAPI class to connect to Coreseek, and perform search operations. First, we need to instantiate a SphinxAPI object and set the Coreseek connection parameters.

// 连接到Sphinx
$sphinx = new SphinxAPI();
$sphinx->setServer("localhost", 9312);
  1. Set search keywords

Next, we need to set search keywords. The matching mode can be set by calling the SetMatchMode method of the SphinxAPI object.

// 设置匹配模式
$sphinx->SetMatchMode(SPH_MATCH_ALL);
// 设置搜索关键词
$keyword = "手机";
$sphinx->SetMatch($keyword);
  1. Perform search operation

After completing the settings, we can call the Query method of the SphinxAPI object to perform the search operation. The Query method will return an array containing the search results.

// 执行搜索操作
$result = $sphinx->Query("", "products");

The first parameter is an empty string, which means querying all fields; the second parameter is the index name, which specifies the data source to be searched.

  1. Processing search results

The search result is an array containing multiple matching documents. We can use a foreach loop to iterate through the results and output the corresponding information.

// 处理搜索结果
foreach ($result["matches"] as $docid => $info) {
    // 获取商品信息
    $product = getProductById($info["id"]);
    
    // 输出商品名称和价格
    echo $product["name"] . " - " . $product["price"] . "元";
}

4. Example Application

Let’s take a simple e-commerce shopping website as an example to demonstrate how to use PHP and Coreseek to achieve efficient search functions.

  1. Database structure

First, we create a database table to store product information.

CREATE TABLE `products` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `price` decimal(10,2) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  1. Index file configuration

We add the following configuration to the Coreseek configuration file to specify the data source we want to search.

source products
{
    type            = mysql
    sql_host        = localhost
    sql_user        = root
    sql_pass        = password
    sql_db          = database
    sql_port        = 3306

    sql_query       = 
        SELECT id, name, price 
        FROM products

    sql_attr_float  = price
}
  1. PHP code example

In the PHP code, we first connect to Sphinx, then set the search keywords and perform the search operation.

// 连接到Sphinx
$sphinx = new SphinxAPI();
$sphinx->setServer("localhost", 9312);

// 设置匹配模式
$sphinx->SetMatchMode(SPH_MATCH_ALL);
// 设置搜索关键词
$keyword = "手机";
$sphinx->SetMatch($keyword);

// 执行搜索操作
$result = $sphinx->Query("", "products");

// 处理搜索结果
foreach ($result["matches"] as $docid => $info) {
    // 获取商品信息
    $product = getProductById($info["id"]);
    
    // 输出商品名称和价格
    echo $product["name"] . " - " . $product["price"] . "元";
}

// 根据商品ID从数据库中获取商品信息
function getProductById($id) {
    // 从数据库中查询商品信息
    // 返回一个包含商品信息的数组
    return array("name" => "iPhone X", "price" => 8999);
}

Through the above steps, we have implemented a simple e-commerce shopping search function. Users can enter keywords to search, and the system will return a list of products related to the keywords.

Summary

This article introduces how to use PHP and Coreseek to implement efficient e-commerce shopping search function. By connecting to Coreseek, setting search keywords, and performing search operations, we can obtain a list of products related to the keywords. Such search functions can provide a better user experience and improve the efficiency and competitiveness of e-commerce websites and applications.
