Sphinx is an efficient search engine. The word segmentation search speed is relatively fast. The index is created and stored in the hard disk file. It will not interfere with the database. It has its own set of built-in databases. I hope it can help everyone.

1. Install sphinx on ubuntu
If aptitude is not installed, you need to install aptitude first because problems will occur when using apt get install to install the following command.<br> sudo apt-get install aptitude
<br>sudo aptitude install sphinx3 sphinx3-doc sphinxsearch sphinx-common -y
2. Configuration
<br> 1 2 |
<br> cd /etc/sphinxsearch/ cp sphinx.conf. sample sphinx.conf |
Modify the configuration file as follows<br>
123 4567891011 121314151617181920212223242526272829303132 33343536373839404142434445464748495051 |

-
Execute the word segmentation command and a bunch of index files will be generated in the /var/lib/sphinxsearch/data/test1 directory<br>
sudo indexer - c /etc/sphinxsearch/sphinx.conf test1
test1 is the index name of the above configuration file
4. Command line test Search
sudo search -c /etc/sphinxsearch/sphinx.conf google
2. Use
in php 1. Install php sphinx Dependent libraries
1. Install aptitude
apt-get install aptitude
<br>sudo aptitude install libsphinxclient-dev libsphinxclient-0.0.1 -y
2. Install php sphinx extension
Install pecl<br>sudo apt-get install php-pear php5-dev
<br>Install sphinx<br>sudo pecl install sphinx
3. Add the sphinx extension to the configuration file php.ini,
My php.ini file is <br> sudo vim /etc/php5/fpm/php.ini
<br>Get your own php.ini file location using<br>php5-fpm -i|grep ini
Add:<br>extension=sphinx.so
<br>4. Restart php5-fpm and check whether php loads the sphinx module<br>sudo /etc/init.d/php5 -fpm restart
<br>5. Run the search program in the background<br>sudo searchd -c /etc/sphinxsearch/sphinx.conf
<br>Default listening port in the configuration file: 9312
6. Call search in thinkphp<br>
123 45678910111213 | public function testSphinx(){$s = new \SphinxClient;$s->setServer("localhost", 9312);$s->SetArrayResult (true ); $s->setMatchMode(SPH_MATCH_ANY);$s->setMaxQueryTime(3);$result = $s->query("test"); $result = $result['matches'];$result = array_column($result,'id');$list = M('CouponApi')-> ;field('couponid,title,description')->where(array('couponid'=>array('in',$result)))->select();dump( $list);} |
$ s->SetLimits(0, 1000, 1000);), the search speed is quite fast, and it takes less than 10 seconds to index the title and description fields of 800,000 pieces of data. The search engine supports incremental indexing and a variety of For pattern search, there is a lot of information on the Internet

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
