How to use PHP and Xunsearch to achieve efficient full-text search function
Introduction: With the continuous development of the Internet and the rapid increase in the amount of information, the full-text search function has become an indispensable part of many websites and applications. This article will introduce how to use PHP and Xunsearch, an open source full-text search engine library, to implement efficient full-text search functions. We'll demonstrate how to create an index, perform a search operation, and display the results, along with relevant code examples.
Part One: Install and Configure Xunsearch
First, we need to install Xunsearch and configure it into our PHP environment.
- Download Xunsearch: First, download the latest version of the installation package from the official website of Xunsearch (http://www.xunsearch.com).
- Extract the installation package: Extract the downloaded installation package to a suitable directory, such as /var/xunsearch.
- Configure Xunsearch: Enter the unzipped directory and copy the
Demo.ini
file in theapp
subdirectory and rename it toyour-app .ini
, then edit theyour-app.ini
file and make relevant configurations according to your needs, such as specifying the path for data storage, setting the retrieval weight of the search engine, etc. -
Start the Xunsearch service: In the terminal, enter the Xunsearch installation directory and run the following command to start the Xunsearch service:
./bin/xs-ctl.sh -b your-app.ini
- Xunsearch PHP extension: Install the Xunsearch PHP extension so that we can Xunsearch functionality can be used in PHP. This extension needs to be added when compiling PHP. You can specify the Xunsearch installation directory by adding the
--with-xs[=DIR]
parameter after theconfigure
command.
Part 2: Create Index
Before using Xunsearch for full-text search, we need to create an index first so that the search engine can provide us with accurate search results.
-
Create an index configuration file: First, create a file named
your-index.ini
to configure the field information and attribute settings of the index. The following is an example:[title] type = title tokenizer = full index = self highlight = full [content] type = bodytext tokenizer = none index = both highlight = full
In the above configuration, we defined two fields:
title
andcontent
, and specified their type, tokenizer, and index Type and highlight type. You can customize the index configuration as needed. -
Use Xunsearch’s Indexer tool to create an index: Enter the Xunsearch installation directory and run the following command to create an index:
./sdk/php/bin/xs-indexer your-index.ini --create
Part 3: Execution Search Operation
Now that we have created the index, we will demonstrate how to perform a search operation in PHP.
-
Connect to the search engine: Using the
XSDocument
class provided by the Xunsearch PHP extension, we can connect to the search engine and perform search operations:<?php require_once('Xunsearch/sdk/php/lib/XS.php'); $xs = new XS('your-app'); //替换为你的应用名 $search = $xs->search;
Here, we create an
XS
instance and obtain theXSSearch
instance through thesearch
attribute. -
Perform a search: Use the
setQuery
method of thesearch
instance to set the search keywords, and use thesearch
method to perform the search Operation:<?php $search->setQuery('keyword'); $searchResult = $search->search();
-
Processing search results: After obtaining the search results, we can traverse the results and print them out or perform other processing:
<?php foreach ($searchResult as $item) { echo "匹配文档ID:" . $item->docid . PHP_EOL; echo "标题:" . $item->title . PHP_EOL; echo "内容:" . $item->content . PHP_EOL; // ...其他字段 }
Summary:
Using PHP and Xunsearch, we can easily implement efficient full-text search functions. By creating indexes, performing searches, and processing results, we provide our users with an accurate and fast search experience. I hope this article will be helpful to you in developing full-text search functions using PHP and Xunsearch.

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

在PHP中,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
